Is voter fraud a problem in the US?

No, voter fraud is not a significant or systemic problem in U.S. elections. It occurs at extremely low rates—typically measured in thousandths or hundred-thousandths of a percent of ballots cast—is almost always isolated rather than organized, is usually detected through existing safeguards, and has not been shown to alter the outcomes of modern federal or statewide elections.[1]

Key Evidence from Studies and Databases

Multiple analyses, including those using data from the conservative Heritage Foundation’s Election Fraud Database (which tracks proven cases ending in convictions, diversions, civil penalties, or official findings), reach the same conclusion:

•The Heritage database lists roughly 1,500–1,620 proven instances spanning decades (from the 1980s onward, across hundreds of millions to over 2 billion ballots in federal elections alone). This equates to rates on the order of a few cases per 10 million ballots (around 0.00007% or lower in broader contexts).[2]
•Brookings Institution analyses of Heritage data for competitive states show minuscule rates with no outcome-altering impact. Example: Arizona had 36 cases over 25 years and ~42.6 million ballots (0.0000845%); Pennsylvania had 39 cases over 30 years and >100 million votes. Similar patterns hold elsewhere. No U.S. election outcome has been altered by ballot fraud per these reviews.[1]
•Brennan Center reviews of studies find impersonation fraud rates of 0.0003%–0.0025%. A person is more likely to be struck by lightning than to successfully impersonate a voter at the polls. A Washington Post investigation found 31 credible impersonation cases out of >1 billion ballots (2000–2014).[2]
•Department of Justice reviews of early 2000s federal elections found fraud rates around 0.00000013%, with no coordinated efforts.[2]
•Mail-in/absentee fraud is also rare: Brookings estimated ~4 cases per 10 million mail ballots across 2016–2022 elections. Studies in all-mail states (e.g., Oregon) show negligible rates relative to volume.[3]
•Noncitizen voting: Proven cases are very few. Heritage has documented dozens over many years (e.g., ~24 convictions 2005–2025 in one count; broader noncitizen cases in the low hundreds historically). Recent Trump administration enforcement has led to ~180 charges (many involving lawful permanent residents or claims of confusion/honest mistakes, with no evidence of organized partisan schemes), plus investigations of more—but these remain a tiny fraction of tens of millions of votes and show no scale capable of tipping elections.[3]

AP reviews of 2020 battleground states found fewer than 475 potential fraud cases amid millions of votes—far too few to affect results (Biden’s margins were hundreds of thousands). Courts, audits, bipartisan officials, and statistical analyses have repeatedly rejected claims of widespread 2020 (or other) fraud.[4]

Fraud does occur occasionally (e.g., individual double-voting, felon voting where restricted, small-scale vote-buying in local races, or rare absentee misuse). Some historical local or primary races (decades ago) involved enough irregularities to affect outcomes. Databases capture only proven cases, so undetected fraud exists in theory, but extensive audits, cross-checks (e.g., ERIC data matching), signature verification, voter roll maintenance, bipartisan observation, and post-election risk-limiting audits provide strong detection. Experts across the spectrum note the incentives and risks (felony penalties, detection likelihood) deter large-scale efforts.[4]

Context and Safeguards

U.S. elections are decentralized (run by states/localities) with layered protections: registration requirements, ID rules (varying by state), provisional ballots, chain-of-custody for ballots, bipartisan poll workers, and prosecutions. Errors (clerical mismatches, outdated rolls) are sometimes mislabeled as fraud. Perceptions of a “problem” often stem from partisan claims rather than data; surveys show large partisan gaps in beliefs about fraud prevalence.[2]

Vigilance, clean voter rolls, secure processes, and prosecution of actual cases are worthwhile for public confidence. However, the data consistently show voter fraud is not rampant, not outcome-determinative at scale, and not a core threat to U.S. election integrity compared to other issues like access, administration errors, or foreign influence attempts. Claims of massive fraud have been investigated exhaustively and found unsupported.
