This year’s filing deadline for candidates running for Congress in Colorado was March 19, 2024.

Thirty-two candidates are running for Colorado’s eight U.S. House districts, including 12 Democrats and 20 Republicans. That’s 4.00 candidates per district, more than in the previous three election cycles. There were 3.75 candidates per district in 2022, 2.28 candidates per district in 2020, and 3.43 in 2018.

Here are some other highlights from this year’s filings:

• The number of candidates running for the U.S. House in Colorado this year is also higher than any other year this decade.

• The 3rd and 5th Congressional Districts are open, meaning no incumbents are running in those districts.
• Rep. Lauren Boebert (R-3rd) is running for the 4th Congressional District, which Ken Buck held before he resigned from Congress on March 22. Rep. Doug Lamborn (R-5th) is not running for re-election because he is retiring from public office.
• Nine candidates—three Democrats and six Republicans—are running for the 4th Congressional District, the most candidates running for a seat in Colorado this year.
• Seven primaries—three Democratic and four Republican—are contested this year. That’s less than the eight contested primaries in 2022 but more than the two contested primaries in 2020.
• Two incumbents—Reps. Diana DeGette (D-1st) and Boebert—are in contested primaries this year. That’s less than the four incumbents in contested primaries in 2022 but more than the one incumbent in a contested primary in 2020.
• Candidates filed to run in the Republican and Democratic primaries in all eight districts, meaning no seats are guaranteed to either party.

Colorado and two other states—New York and Utah—are holding primary elections on June 25.

In Colorado, the winner of the primary election is the candidate who receives the greatest number of votes cast even if they do not win an outright majority.
