As of recent election cycles, 36 states have some form of voter-ID law; about half are "strict" (requiring specific photo IDs with limited fallback options) and the rest are non-strict. The federal HAVA Act of 2002 already requires first-time mail-registered voters to provide identification.
Empirical evidence on in-person voter impersonation finds it exceedingly rare; studies dispute whether ID laws meaningfully reduce turnout, with most rigorous estimates in the 0–3% range, often concentrated among low-income, elderly, and minority voters who are less likely to have current photo ID.
Proposals range from universal automatic photo-ID issuance to abolition of ID requirements entirely.
