If you mean the 2020 U.S. presidential election: yes, the available evidence indicates it was conducted fairly and that the certified result was accurate.
Election officials from both parties, recounts and audits in key states, and numerous court cases found no evidence of fraud or irregularities on a scale that could have changed the outcome. Federal election-security officials described it as “the most secure in American history.” As in any large election, isolated errors and improper votes occurred, but they were investigated and were not outcome-determinative.
Your choice of candidate does not affect that assessment.
