More than half a million Coloradans have already voted in the 2026 midterm election, according to the first turnout report from the secretary of state’s office.

As of late Monday, 509,364 voters already submitted their ballots — good for about 12.6% of all active voters in Colorado. Most ballots returned have been mail ballots.

Democrats outpace Republican voters with 33.4% of ballots returned so far compared to 24.2%. Unaffiliated voters, who represent just over half or all registered voters in Colorado, make up 41.3% of ballots returned.

Early turnout from all parties so far is outpacing the 2022 midterm elections, while unaffiliated and Democratic turnout also outpaces 2024.
