Is voter fraud a problem in the US?

Leans no

Short answer: Rare but real—and not at levels shown to change national outcomes.

What the research shows

•Multiple studies have found proven voter fraud rates to be extremely low—on the order of roughly 0.0003% to 0.0025% of ballots in studied elections. Most alleged “fraud” turns out to be clerical error, voter confusion, or bad data matching, not intentional cheating.[1]

•Still, isolated cases do occur. A well‑known example is North Carolina’s 9th Congressional District in 2018, where absentee‑ballot manipulation led the state board to throw out the results and order a new election.[2]

Context and perspectives

•The Heritage Foundation maintains a database of prosecuted election‑fraud cases (convictions, plea deals, or official findings). It shows that fraud exists across categories (e.g., absentee‑ballot abuse, vote buying, registration offenses), but the counts span many decades and remain tiny relative to the hundreds of millions of ballots cast.[3]

•News and official reviews repeatedly report no evidence of widespread fraud in recent U.S. elections, even as isolated cases are pursued.[4]

Bottom line: In the United States, proven voter fraud happens occasionally—more often in specific contexts like absentee ballots and very close local races—but rigorous studies and official reviews have not found evidence of large‑scale fraud altering national election outcomes.[1]

If you’d like, I can break down the main fraud types, how states try to prevent them, and what the evidence says about each.
