Did you vote in this year's midterm elections in your area?

Colorado's 2026 midterm voter turnout reached 67.3% of registered voters as of Monday, according to county clerks' ballot processing totals. The figure exceeds turnout in 2022 but trails the nearly 75% recorded in 2018.

Why it matters

The turnout level places Colorado's midterm participation between its recent 2022 and 2018 benchmarks, offering a measure of how engaged the state's electorate was in this cycle. Party-by-party and age-group figures show differences in participation across the state's voter blocs.

The figures are drawn from county clerk ballot processing as of Monday, with about 95% of returned ballots being mail ballots. Final participation totals remain pending as daily reports continue through Thursday.

The players

Colorado Secretary of State's Office

The state office responsible for overseeing Colorado elections, which compiled county turnout data and issues the state's daily turnout reports.

The details

County clerks processed 2.76 million ballots from Colorado voters as of Monday. Nearly 600,000 voters aged 18 to 34 participated, a 48% rate compared with 45% in the 2022 midterms, while more than 920,000 voters aged 55 to 74 also cast ballots.

2018: Midterm turnout reached nearly 75% of active voters in Colorado.
2022: Midterm turnout reached a little more than 66% of active voters in Colorado.
Monday (November 9, 2026): Turnout reached 67.3% with 2.76 million ballots processed.
Through Thursday (November 12, 2026): The secretary of state's office sends daily turnout reports.

Political Context

Colorado's 2026 turnout falls between the roughly 66% recorded in 2022 and the nearly 75% recorded in 2018, a pattern that marks a partial recovery from the earlier midterm cycle without matching its peak. Participation gaps among Democratic, Republican and unaffiliated voters also shape how the overall figure compares with earlier cycles.

Turnout data helps residents see how many neighbors participated in the midterms and how voter groups compare. Voters who have not yet confirmed their ballot status can check the secretary of state's reporting as interim totals continue to update.

The takeaway

Turnout is still being counted, so the 67.3% figure reflects a snapshot rather than a final result. Watching the daily reports can show whether participation rises further before the count closes.

What happens next

The Colorado secretary of state's office will continue issuing daily turnout reports through Thursday, November 12, 2026, which may update the 67.3% figure.
