Is voter fraud a problem in the US?

Short answer: Voter fraud exists in the U.S., but credible research and official reviews consistently find it to be rare and not widespread. It can matter in a few close, usually local races, but there’s no evidence it’s a systemic, national-scale problem.

What the evidence shows

•Overall incidence is very low. One well‑known review found 31 credible cases of in‑person voter impersonation out of more than 1 billion ballots cast from 2000–2014.[1]

•Mail voting has vulnerabilities but documented fraud rates are also very low; large analyses find no evidence that vote‑by‑mail increases fraud overall.[2]

•High‑profile audits and recounts have repeatedly confirmed statewide results. For example, Georgia’s 2020 presidential race underwent a full hand count across all 159 counties and confirmed the original outcome. The Carter Center observed the process.[3]

•Federal agencies reviewing 2020 reported no evidence that anyone changed votes or prevented voting by compromising election infrastructure.[4]

•Proven cases do occur and are prosecuted. Databases of convictions and official actions exist, and a few close races have been overturned or redone due to absentee‑ballot schemes (e.g., North Carolina’s 9th Congressional District in 2018; a Paterson, NJ city council race in 2020). These are notable precisely because they’re unusual.[5]

•Election administrators use multiple safeguards—ID or signature checks (depending on state), ballot tracking, bipartisan observers, and post‑election audits—to deter and catch problems. Research groups like the Caltech/MIT Voting Technology Project document such controls and detection methods.[6]

Bottom line

•Is voter fraud a problem? It exists and should be deterred and prosecuted, but the best available data indicate it is rare and not a large‑scale threat to national election outcomes. Targeted safeguards and audits address the genuine risks without exaggerating their frequency.[1]

If you want, I can tailor this to your state and the specific safeguards and recent cases (if any) there.
