Iowa had 1,855,812 active registered voters on November 1, 2026, according to the Secretary of State's office. Registered Democrats, independents, and Republicans each grew in number from October 1.

Why it matters

Registration totals offer a snapshot of the partisan makeup of the electorate heading into Election Day on November 3, 2026. Republicans, at just over 38.5% of registered voters, remain the largest bloc in the state.

Republicans gained about 3,800 registrants and Democrats about 8,700 between October 1 and November 1, 2026, while independent or no-party registrations rose by nearly 11,000. Final turnout and party-level vote shares remain unknown until ballots are counted.

The players

Iowa Secretary of State's Office

The state office responsible for maintaining Iowa's voter registration database and publishing monthly registration totals.

The details

The Iowa Secretary of State's office updates voter registration data at the start of each month. Election workers may begin counting absentee ballots the morning of Election Day, though absentee ballots must reach county auditors' offices by 8 p.m. when polls close to be counted.

Timeline

  1. October 1, 2026: Prior monthly voter registration totals were recorded.

  3. November 3, 2026: Election Day; polls are open 7 a.m. to 8 p.m.

Political Context

The monthly publication cycle of the Iowa Secretary of State's office gives a consistent baseline for tracking partisan registration shifts. Republicans have held the registration lead in the state, and the latest monthly gains show growth across all three major registration categories.

Registered voters must have their ballots in hand or cast them in person by the 8 p.m. close on Election Day. Absentee ballots not received by county auditors' offices by that time will not be counted.

The takeaway

Voters who want their ballots counted should confirm their registration status and mail or deliver absentee ballots well before 8 p.m. on Election Day.

What happens next

Election Day is November 3, 2026, when polls open at 7 a.m. and close at 8 p.m., and absentee ballots must arrive by 8 p.m. to be counted.
