Is voter fraud a problem in the US?

No, voter fraud is not a significant or systemic problem in the US. It occurs at extremely low rates (typically measured in thousandths or millionths of a percent of ballots cast), is usually detected and prosecuted when it happens, and has not been shown to alter the outcomes of major federal elections (such as presidential races) in modern times. Isolated incidents do occur, particularly in smaller local races with thin margins, but extensive data from government investigations, academic studies, nonpartisan analyses, and even databases compiled by groups concerned about fraud confirm it is rare.[1][2][3]

Key Data and Studies

Context on Impacts and Safeguards

Researchers and officials (across parties and administrations) note that while fraud is unacceptable and should be prosecuted, it is not systemic or organized in a way that sways major outcomes. Local races can occasionally be affected or lead to new elections (e.g., the 2018 North Carolina congressional race due to an absentee ballot scheme, or some municipal cases), but this is exceptional and typically involves closer scrutiny in low-turnout contests. No modern presidential election outcome has been shown to turn on documented voter fraud.[13][14]

US elections have multilayered safeguards: voter registration checks, ID or affidavit requirements (varying by state), signature verification for mail ballots, poll books, bipartisan observers, audits/risk-limiting audits, chain-of-custody rules, post-election canvassing, and criminal prosecution by state/federal authorities (DOJ has charged individuals for illegal voting, false registration, etc.). CISA and election officials have repeatedly affirmed that election infrastructure is secure, with no evidence of malicious activity materially impacting recent election integrity or results.[3][15]

Perceptions vs. Reality

Public belief in widespread fraud remains higher than the data support, especially along partisan lines (often fueled by high-profile claims after close or disputed elections). Surveys show substantial minorities view various fraud types as common, which can erode trust even without evidence. Many alleged “fraud” reports turn out to be administrative errors, data mismatches, or misunderstandings rather than intentional crime. Exaggerated claims can lead to policies that burden eligible voters without addressing real (rare) risks.[16][11]

In short, voter fraud exists at a low level—like other low-rate crimes—and merits ongoing enforcement and process improvements. However, the overwhelming body of evidence from diverse sources shows it is not a meaningful threat to the integrity or outcomes of US elections at scale. Election officials, courts, and researchers of varying perspectives consistently reach this conclusion.
