Is voter fraud a problem in the US?

No, voter fraud is not a significant or widespread problem in the United States. Documented cases occur at extremely low rates—typically measured in thousandths or hundred-thousandths of a percent of ballots cast—and there is no credible evidence that it has altered the outcomes of modern federal elections (presidential or congressional).[1]

Key Evidence from Studies and Databases

Multiple independent analyses, government investigations, academic research, and even data from the conservative Heritage Foundation’s Election Fraud Database (which compiles proven cases resulting in convictions, civil penalties, judicial findings, or similar) consistently show fraud is rare:

•The Brennan Center for Justice, reviewing numerous studies, found voter fraud incident rates (especially impersonation) between roughly 0.0003% and 0.0025%. An American is more likely to be struck by lightning than to impersonate another voter at the polls.[2]

•A 2014 Washington Post investigation identified only 31 credible instances of in-person impersonation fraud out of more than 1 billion ballots cast from 2000–2014.[2]

•Brookings Institution analyses using Heritage’s own data found tiny rates in key states. In Arizona, 36 proven cases over 25 years and more than 42 million ballots (rate of about 0.0000845%). In Pennsylvania, 39 cases over 30 years and more than 100 million votes. No election outcomes were altered by ballot fraud in these reviews.[1]

•Heritage’s database (updated as of late 2025) lists roughly 1,600–1,620 proven instances of various election fraud types (including absentee ballot misuse, false registration, ineligible voting, duplicate voting, vote buying, etc.) going back decades (to the 1980s or earlier in some cases). This spans hundreds of millions to billions of ballots cast nationwide. It is a sampling, not exhaustive, but even taken at face value the rate is minuscule (on the order of a few cases per 10 million ballots). Many cases involve single individuals or small schemes, often in local races.[2]

•After the 2020 election, an Associated Press review of potential fraud cases in six battleground states found fewer than 475 problematic votes out of more than 25 million cast—far too few to affect results.[3]

•Mail-in/absentee fraud is also rare. Brookings estimated an average of about four cases per 10 million mail ballots across recent general elections. Noncitizen voting is vanishingly rare (Heritage lists around 100 cases over decades; state audits and studies find rates near zero).[4]

A Department of Justice review of early 2000s federal elections found a fraudulent ballot rate of about 0.00000013%, with no coordinated efforts to sway outcomes. Other multi-state reviews (e.g., examining tens of millions of votes) similarly yield handfuls of referrals for prosecution.[2]

Context and Caveats

•Fraud does happen occasionally and is illegal. Cases include double voting, voting while ineligible (e.g., felons in some states, noncitizens), absentee ballot misuse, or rare impersonation. When detected, it is typically prosecuted (recent DOJ actions have charged small numbers of individuals, including noncitizens, for illegal voting or related crimes). Isolated local elections have occasionally been overturned or required new votes due to fraud or irregularities.[5]

•Safeguards exist and work: These include voter registration checks, ID requirements (in many states), signature verification for mail ballots, provisional ballots, poll books, cross-state data sharing (e.g., via ERIC where used), post-election audits, bipartisan observation, chain-of-custody rules, and criminal penalties. Most votes now have paper trails. Election officials (from both parties) and cybersecurity agencies have repeatedly affirmed the security and integrity of recent elections.

•Allegations vs. evidence: High-profile claims of widespread or outcome-determinative fraud (especially around 2020) have been investigated extensively via audits, recounts, court cases (dozens dismissed for lack of evidence), and reviews by Trump administration officials, state officials, the DOJ, CISA, and others. They have not held up. Many “irregularities” turn out to be administrative errors, data mismatches, or misunderstandings rather than intentional fraud.[6]

•Local vs. national: Small-scale fraud is more likely to matter in low-turnout local races with thin margins than in statewide or federal contests involving millions of votes.

In short, while perfect zero-fraud elections are impossible in any large system and vigilance/integrity measures remain essential, the data show voter fraud is not a systemic threat capable of changing U.S. election results at scale. Claims otherwise are not supported by the evidence from nonpartisan researchers, government bodies, courts, or even compilations of proven cases by groups seeking to highlight the issue. Public confidence benefits from accurate information, transparent processes, and focusing on real (rather than exaggerated) vulnerabilities.
