Below are the criticisms most commonly leveled at the Biden administration, including by analysts and Democrats themselves. "Failure" involves value judgments, so I've tried to note where causation is genuinely disputed.
## 1. Inflation and the cost-of-living crisis
Inflation peaked at 9.1% (CPI, June 2022), the highest in four decades, and cumulative price increases of roughly 20% over the term became the dominant political fact of the presidency. Criticisms:
- The $1.9 trillion American Rescue Plan (March 2021) was arguably too large for an economy already recovering — a warning made at the time by Democratic economists Larry Summers and Jason Furman.
- Administration officials, along with the Fed, spent much of 2021 insisting inflation was "transitory," delaying policy response.
- Real wages fell for roughly two years before recovering, and the administration's messaging about a strong economy struck many voters as out of touch.
Counterpoint: supply-chain disruption, energy shocks from Russia's invasion, and pandemic savings drove much of it; U.S. inflation was comparable to or lower than peers with smaller stimulus.
## 2. The Afghanistan withdrawal
The decision to leave was broadly popular; the execution was not. Kabul fell on August 15, 2021, faster than intelligence and administration officials had publicly predicted. The Abbey Gate suicide bombing killed 13 U.S. service members and roughly 170 Afghans. An August 29 retaliatory drone strike killed 10 civilians, including seven children. Thousands of Afghan allies and some American citizens were left behind, and billions in equipment was abandoned. It was the sharpest and most durable drop in Biden's approval rating, from which he never recovered.
## 3. Immigration and the southern border
Border encounters reached record levels — roughly 2.5 million at the southwest border in FY2023, with a single-month record in December 2023. The administration was slow to treat this as a crisis, spent years without a coherent asylum-processing strategy, and left cities like New York and Chicago absorbing large numbers of migrants. The June 2024 executive action that sharply reduced crossings was effective but came three years late, undercutting the argument that legislation was strictly necessary. Immigration advocates, meanwhile, criticized the administration from the left for retaining Title 42 and then adopting restrictions resembling Trump-era policies.
## 4. Running for reelection, and the handling of his own decline
Many Democrats now regard this as the administration's defining failure. Biden ran for a second term at 81 despite promising to be a "bridge" to a new generation; his inner circle limited his public exposure and dismissed concerns about his acuity as partisan attacks; Special Counsel Robert Hur's February 2024 report described him as "an elderly man with a poor memory." After the June 27, 2024 debate, he withdrew on July 21, leaving Kamala Harris roughly 100 days with no primary and no opportunity for the party to select an alternative. The result was the loss of the presidency, Senate, and House to the person Biden had described as an existential threat to democracy.
## 5. Legislative overreach and unkept promises
With a 50-50 Senate, the administration repeatedly promised more than it could deliver:
- **Build Back Better** collapsed in 2021 before being salvaged in reduced form as the Inflation Reduction Act.
- **Voting rights** legislation failed when a filibuster carve-out lost 48-52 in January 2022 (Manchin and Sinema), after a campaign in which Biden had elevated the issue to a democratic emergency.
- **Codifying Roe** never happened despite the promise; the administration was also unprepared for the *Dobbs* decision despite the leaked draft.
- Police reform, the PRO Act, and a federal minimum wage increase all died.
## 6. Student loan forgiveness
The $430 billion plan was struck down in *Biden v. Nebraska* (2023) on grounds many legal scholars had flagged in advance. Subsequent workarounds were also enjoined. The net effect was raised expectations, repeated payment-pause extensions costing tens of billions, and no durable policy — while doing little for the voters it targeted.
## 7. Slow implementation of the signature legislation
The infrastructure law, CHIPS Act, and IRA were real achievements, but delivery was poor enough to become a case study in state capacity:
- The $7.5 billion EV charger program had produced only a few dozen operational stations by late 2024.
- The $42.45 billion BEAD broadband program had connected zero households by the end of the term.
- Permitting, Buy American rules, and layered social requirements ("everything-bagel liberalism," in Ezra Klein's phrase) slowed projects and raised costs.
Voters largely never experienced the benefits before voting.
## 8. Gaza and the Middle East
October 7, 2023 and its aftermath exposed the collapse of the administration's bet that the region could be de-prioritized. Critics argue Biden set public "red lines" for Israeli conduct in Rafah and on humanitarian access, then declined to enforce them, forfeiting leverage while absorbing responsibility for a catastrophic civilian toll. A ceasefire and hostage deal broadly resembling U.S. proposals wasn't reached until the transition. The $230 million floating pier operated intermittently for about three weeks before being dismantled. Efforts to revive the Iran nuclear deal failed, sanctions enforcement on Iranian oil was lax, and Houthi attacks closed the Red Sea to much commercial shipping despite months of U.S. strikes. The political cost within the Democratic coalition — the "uncommitted" movement, depressed turnout among young and Arab American voters — was significant.
## 9. Ukraine: incrementalism
Critics on the right argue deterrence failed before February 2022 (including the pre-invasion signal that a "minor incursion" might prompt a lesser response). Critics on the national-security left and center argue aid was too slow and too incremental — HIMARS, ATACMS, Abrams, F-16s, and long-range strike permissions each arriving after months of internal debate over escalation, giving Russia time to adapt and entrench. The administration also failed to lock in long-term funding before losing the House, resulting in a six-month aid lapse in 2024.
## 10. Fiscal policy
Deficits ran roughly $1.8 trillion in FY2024 at full employment, debt held by the public approached 100% of GDP, and net interest costs surpassed defense spending. The administration proposed no serious consolidation and made no progress on Social Security or Medicare solvency.
## 11. Housing and affordability
Housing affordability reached its worst level on record. The administration's response arrived late, was largely rhetorical or dependent on Congress, and some measures (like proposed rent caps) were criticized by economists as counterproductive.
## 12. Norms, credibility, and the "unity" promise
The core 2020 promise — to lower the national temperature and restore normalcy — was not fulfilled; polarization and distrust in institutions were as bad or worse by 2025. Specific self-inflicted wounds included the pardon of Hunter Biden after repeatedly promising not to, the unprecedented preemptive pardons of allies and family, and the appearance of a "no-drama" administration that concealed information (Defense Secretary Austin's undisclosed hospitalization in January 2024 being the clearest case).
## Other frequently cited items
- COVID stumbles: at-home test shortages during Omicron, the OSHA vaccine mandate struck down by the Supreme Court, deference to teachers' unions on school reopening, and continued erosion of CDC credibility.
- The overdose crisis: deaths peaked above 110,000 annually before declining in 2024; critics faulted slow action on fentanyl precursors from China.
- Energy policy that satisfied neither side — the LNG export permit pause and Keystone cancellation alongside record U.S. oil production.
- China policy: the February 2023 spy balloon incident, and limited progress despite export controls.
---
A fair accounting would set these against real accomplishments — a historically fast labor-market recovery, inflation returning near target without a recession, the largest infrastructure and climate investments in decades, NATO's expansion and cohesion, and the first significant gun legislation in 30 years. But on the criteria the administration itself set — beating inflation, restoring competence and normalcy, and preventing a Trump restoration — the record includes several major and consequential failures.

Assessments of any administration vary by political perspective, but here are the criticisms most commonly raised — including several acknowledged across the political spectrum and by Biden's own allies.
**1. The Afghanistan withdrawal (August 2021)**
Probably the most widely agreed-upon failure. The Afghan government and army collapsed far faster than U.S. intelligence and military planning anticipated, producing chaotic scenes at Kabul airport, a suicide bombing that killed 13 U.S. service members and roughly 170 Afghans, and thousands of Afghan allies left behind. Subsequent reviews faulted interagency planning, the timing of the embassy drawdown, and the failure to begin evacuating visa applicants earlier. Biden's approval rating never recovered to its pre-withdrawal level.
**2. Inflation and cost-of-living**
Inflation peaked at about 9.1% in mid-2022, the highest in four decades, and cumulative price increases in groceries, rent, and energy became the dominant political grievance of the era. The administration initially dismissed inflation as "transitory." Economists disagree about causation — supply chains, pandemic demand shifts, and energy shocks from Russia's invasion all contributed — but Democratic economists including Larry Summers and Jason Furman argued the $1.9 trillion American Rescue Plan, passed when the economy was already recovering, was excessive and overheated demand.
**3. Border security and immigration**
Southwest border encounters reached record highs, exceeding 2 million annually for several years. Trump-era policies were rescinded before durable alternatives were in place, asylum processing and immigration courts were overwhelmed, and the administration was widely seen as slow to respond — issuing significant restrictive executive actions only in June 2024, after bipartisan border legislation collapsed. Immigration became one of Biden's worst-polling issues.
**4. The decision to seek reelection, and its handling**
Many Democrats now describe this as the administration's gravest political error. Biden ran for a second term at 81 despite persistent public concern about his age, performed disastrously in the June 2024 debate, and withdrew in late July, leaving Kamala Harris roughly 100 days to campaign with no primary. Subsequent reporting alleged that aides and family managed and obscured signs of decline. The result was Republican control of the presidency, Senate, and House — and the reversal of much of Biden's own agenda.
**5. Unfulfilled legislative promises**
Build Back Better collapsed in 2021 (a smaller version later passed as the Inflation Reduction Act). Voting rights legislation, codification of *Roe*, police reform, the PRO Act, and immigration reform all failed. Critics on the left fault insufficient pressure and strategy; others argue a 50-50 Senate made these goals unrealistic from the start.
**6. Legal overreach and reversals in court**
The Supreme Court struck down the OSHA vaccine mandate, the eviction moratorium, and the flagship $400 billion student debt cancellation plan — the latter after Biden had been advised his authority was doubtful. Critics saw a pattern of announcing legally vulnerable policies for political benefit.
**7. Slow implementation of signature spending laws**
Despite large appropriations, delivery lagged badly. The $7.5 billion EV charger program had built only a few dozen stations by late 2024; the $42 billion broadband program had connected virtually no homes. Permitting obstacles, buy-American rules, and administrative complexity — much of it self-imposed — drew criticism even from sympathetic analysts as evidence of state capacity problems.
**8. Foreign policy beyond Afghanistan**
Critics argue the administration failed to deter Russia's 2022 invasion and then supplied Ukraine incrementally — debating tanks, HIMARS, F-16s, and long-range missiles for months each — prolonging the war without enabling victory. On Gaza, the administration was criticized from opposite directions: for insufficient restraint on Israel, and for pressuring an ally during wartime. Other cited misses include the failed Iran diplomacy, the awkward reversal on Saudi Arabia after calling it a "pariah," and limited progress on Chinese fentanyl precursors.
**9. Pandemic-response missteps**
Test shortages during the Omicron wave, inconsistent CDC guidance on masking and isolation, and slow pressure to reopen schools drew criticism, as did a declared "independence from the virus" in July 2021 that preceded the Delta surge.
**10. Fiscal trajectory**
Annual deficits ran near $1.8 trillion in a full-employment economy and federal debt grew substantially, with no serious effort at entitlement or deficit reform. Interest costs now exceed defense spending.
**11. Norm and credibility controversies**
The pardon of Hunter Biden after repeatedly pledging not to intervene, followed by unprecedented preemptive pardons for allies, was criticized as damaging to the rule-of-law argument central to Biden's own case against his opponent. Defense Secretary Austin's undisclosed hospitalization was another self-inflicted wound.
**12. Failure to communicate or persuade**
Even where the administration claimed success — strong job growth, wage gains eventually outpacing inflation, major industrial legislation — it never converted this into public credit. The "Bidenomics" branding was abandoned, and approval ratings stayed in the high 30s to low 40s for most of the term.
**A caveat on framing:** several items above are genuinely contested rather than settled. Supporters would argue that inflation was a global phenomenon that the U.S. weathered better than most peers, that leaving Afghanistan was an unpopular-but-correct decision poorly executed under a Trump-negotiated deadline, that a one-vote Senate margin made legislative failures inevitable, and that industrial policy investments will pay off over a longer horizon than a single term. Where you land depends partly on how much causal responsibility you assign to presidents for economic and global conditions — a question on which reasonable people disagree.

Here's a rundown of what critics — and in some cases nonpartisan reviewers, courts, and inspectors general — have identified as the biggest shortcomings. I've tried to separate clear-cut failures (goals the administration set and didn't achieve) from contested judgment calls, since "failure" often depends on what you think government should be doing.
## Unmet promises and legislative losses (first term, 2017–21)
- **Repealing the Affordable Care Act.** The central Republican campaign promise for seven years. The July 2017 Senate vote failed (John McCain's decisive "no"), and no replacement plan ever materialized despite unified party control of government.
- **The border wall.** About 450 miles were built, the large majority replacing existing barriers rather than adding new mileage. Mexico never paid for any of it; funding came from redirected Pentagon money, which triggered years of litigation.
- **Infrastructure.** Repeatedly promised, repeatedly postponed; no major bill ever reached Congress. A bipartisan package eventually passed under Biden.
- **Debt and deficits.** Trump pledged to eliminate the national debt in eight years. The debt rose roughly $7.8 trillion, and annual deficits were growing before COVID hit — driven partly by the 2017 tax cuts, which did not generate the promised self-financing growth.
- **Sustained 4%+ GDP growth** never materialized; growth ran roughly 2–3% pre-pandemic.
## Foreign policy
- **North Korea.** Three summits and unprecedented personal diplomacy produced no denuclearization agreement. Pyongyang's nuclear and missile programs expanded during the period.
- **Iran.** Withdrawal from the nuclear deal and "maximum pressure" did not produce a new agreement. Iran subsequently enriched uranium to far higher levels than the deal permitted.
- **The China trade war.** China fulfilled only about 58% of its Phase One purchase commitments. U.S. taxpayers spent roughly $28 billion bailing out farmers hurt by retaliation, and studies by economists at the Fed, Princeton, and Columbia found the tariff costs were borne mainly by American importers and consumers. The overall trade deficit grew.
- **The Doha agreement with the Taliban** (Feb. 2020) excluded the Afghan government, committed the U.S. to full withdrawal, and secured Taliban commitments that were not kept — widely faulted as setting up the collapse that followed in 2021, though the Biden administration's execution shares blame.
## COVID-19
This is the most consequential item and the most argued-over. Roughly 400,000 Americans died before the term ended, and U.S. per-capita mortality was worse than most peer democracies. Specific, well-documented problems:
- Early public downplaying of the threat, which Trump acknowledged on tape to Bob Woodward was deliberate
- A badly botched CDC test rollout in February 2020 that cost weeks of surveillance capacity
- No coherent national testing or PPE strategy; states left bidding against each other
- Public contradiction of his own health officials, and promotion of unproven treatments
- Politicization of CDC guidance documents (later confirmed by congressional investigation)
The counterweight is **Operation Warp Speed**, which most analysts across the spectrum consider a genuine success — vaccines developed and authorized faster than nearly anyone predicted.
## Governance and administrative competence
- **Family separation.** DOJ and DHS inspectors general found the policy was implemented without systems to track separated families. Hundreds of children remained unreunited years later. The administration's own internal warnings were disregarded.
- **Court losses on regulation.** Studies by NYU's Institute for Policy Integrity found the administration lost the large majority of its deregulatory challenges — roughly 75–80% — mostly for failing to follow basic Administrative Procedure Act requirements. This is a competence failure distinct from the policy merits: many rollbacks failed simply because they were done sloppily.
- **Turnover and vacancies.** Record-setting senior staff turnover, heavy reliance on "acting" officials in Senate-confirmable posts, and a striking number of associates convicted of crimes (Manafort, Flynn, Cohen, Stone, Bannon, Navarro).
- **Hurricane Maria.** The Puerto Rico response was slower and less resourced than comparable mainland responses; excess-death estimates reached roughly 3,000.
- **The opioid crisis.** Declared a public health emergency, but overdose deaths rose throughout the term.
- **Blocked initiatives.** The census citizenship question and the DACA rescission were both struck down by the Supreme Court, in part for pretextual or procedurally deficient reasoning.
## The end of the first term
The refusal to accept the 2020 election result, the pressure on state officials and the Vice President, and January 6th are what most historians currently treat as the defining failure of the term — a departure from peaceful transfer of power without modern precedent. Trump's supporters dispute this framing; multiple courts, dozens of election lawsuits, and his own Attorney General found no evidence of outcome-determinative fraud.
Also notable: **two impeachments** (Ukraine, and incitement), and the **Charlottesville "both sides" remarks**, which even many Republican allies criticized at the time.
## Second term (2025 onward)
My information here is limited by my training data, so treat this as incomplete and check current sources. Reported flashpoints have included the April 2025 "Liberation Day" tariff rollout and subsequent market turmoil and partial reversals; legal defeats over deportations conducted without due process; DOGE-driven staffing cuts and their operational consequences; the Signal group-chat security breach; the Epstein files controversy; and the failure of the promised rapid settlement of the Ukraine war.
---
**A caveat worth stating plainly:** you asked for failures, so this is one-sided by construction. A fair overall assessment would weigh these against things supporters count as wins — Warp Speed, three Supreme Court appointments, the Abraham Accords, criminal justice reform via the First Step Act, low pre-pandemic unemployment including record lows for Black and Hispanic workers, and the destruction of ISIS's territorial caliphate. And several items above (tariffs, immigration enforcement, deregulation) are things his voters wanted; calling them failures assumes a policy framework they reject.
Happy to do the mirror-image list, or go deeper on any single item.

Any list like this involves judgment calls, so I'll focus on cases where there's either broad consensus that a stated goal went unmet, or where independent bodies (inspectors general, courts, the GAO, nonpartisan analysts) documented problems. I'm covering the first term (2017–21) in detail; my information on the second term is limited by my knowledge cutoff.
**COVID-19 response**
The U.S. recorded roughly 400,000 deaths by January 2021 and had higher per-capita mortality than most wealthy peers. Widely documented problems included a botched initial CDC test rollout, inconsistent public messaging that at times contradicted government scientists, shortages of PPE and reliance on state-level competition for supplies, and reluctance to use federal procurement authorities early. Operation Warp Speed, by contrast, is generally credited as a success.
**The 2020 election and January 6**
Refusing to concede, promoting fraud claims rejected in dozens of courts (including by Trump-appointed judges), pressuring state officials and the Vice President, and the resulting Capitol attack constitute the failure most frequently cited across party lines — it led to a second impeachment, with seven Republican senators voting to convict.
**Unfulfilled signature promises**
- *Repealing the ACA*: failed in the Senate in 2017 despite unified Republican control.
- *The border wall*: about 450 miles were built, mostly replacing existing barriers, and Mexico did not pay for it. Funds were redirected from military construction after Congress declined to appropriate them.
- *Infrastructure*: repeatedly promised, never introduced as serious legislation.
- *Eliminating the national debt*: debt rose by roughly $7–8 trillion.
**Fiscal outcomes**
The 2017 tax law did not generate the growth needed to pay for itself, per CBO, JCT, and most independent estimates. The deficit grew from about $585 billion (FY2016) to nearly $1 trillion in FY2019 — before pandemic spending — which is unusual during an expansion.
**Family separations at the border**
The DHS and HHS inspectors general found the policy was implemented without adequate planning or tracking systems, leaving thousands of children unaccounted for relative to their parents; some remained unreunited years later. Courts ruled key aspects unlawful.
**Trade policy**
China did not meet roughly 40% of its Phase One purchase commitments. Studies from the Fed, NBER, and others found tariff costs were borne largely by U.S. importers and consumers; the administration paid about $28 billion in farm bailouts to offset retaliation. Manufacturing entered a mild recession in 2019.
**North Korea**
Three historic meetings produced no verifiable denuclearization; North Korea expanded its nuclear and missile programs throughout.
**Iran**
Withdrawal from the JCPOA and "maximum pressure" did not produce a new agreement; Iran subsequently enriched uranium to far higher levels than the deal permitted.
**Afghanistan**
The 2020 Doha agreement was negotiated largely without the Afghan government and set a withdrawal timeline widely criticized as undermining Kabul's position — though the 2021 execution was the Biden administration's.
**Governance and process**
Record cabinet and senior-staff turnover, heavy reliance on "acting" officials (which the GAO found violated the Vacancies Act in some cases), and an unusually high rate of court losses on administrative-law grounds — the census citizenship question, the DACA rescission, and many regulatory rollbacks were struck down for procedural inadequacy rather than substance. The Office of Special Counsel also documented multiple Hatch Act violations.
**Other frequently cited items**
Hurricane Maria recovery in Puerto Rico (an estimated ~3,000 excess deaths, slow aid); rising opioid overdose deaths despite a declared emergency; refusal to divest from business interests; and the Charlottesville response.
**Second term (2025– )**
My knowledge here is incomplete, so I'd treat anything I say as provisional. Early flashpoints included tariff policy and market reaction, the scale and legality of executive-branch restructuring, and immigration enforcement litigation — but you'd want current sources for how those developed.
A caveat worth stating: supporters would contest several of these framings and point to pre-pandemic wage growth (especially at the bottom of the distribution), the Abraham Accords, criminal justice reform, judicial appointments, and Warp Speed. If you want, I can do the parallel list of successes, or go deeper on any single item here.
