US House
Colorado Rep. Diana DeGette (D-Denver)
Under Colorado election procedure, a candidate may qualify for the ballot in two ways. First, receive at least 30 percent support from the party assembly delegates; second, submit 1,500 valid registered voter petition signatures. Candidates can both participate in the assembly and file petitions.
At the 1st Congressional District Assembly this past Saturday, Rep. DeGette received only 33 percent of the delegate vote opposite attorney Melat Kiros.
According to The Down Ballot political blog, 235 delegates were present and voting, meaning just 78 of the participating individuals voted for the 15-term incumbent. The result indicates that she earned ballot placement by just eight votes. Rep. DeGette did not file petitions as a safeguard against performing poorly at the assembly; therefore, she risked renomination defeat had she fallen below the 30 percent threshold.
A third 1st District Democratic congressional candidate, University of Colorado Regent Wanda James, did not participate in the assembly but filed signature petitions.
Therefore, it appears Rep. DeGette has a serious primary challenge in the June 30 Colorado plurality primary election. According to the 2025 year-end Federal Election Commission financial disclosure statement, the Congresswoman held just over $535,000 in her campaign account. Kiros raised over $230,000 and James slightly under $180,000.
Though the delegate vote was overwhelming for Kiros, the assembly result is not necessarily representative of the 1st District Democratic primary vote base. It does show, however, that Kiros is a serious candidate and has significant grassroots support among the most active regular party primary voters.
Rep. DeGette is certainly not the only veteran Democratic incumbent facing a competitive primary challenge. Three, for example, face former US House members. Opposing Reps. April McClain Delaney (D-MD), Wesley Bell (D-MO), and Julie Johnson (TX-33) are former members who previously held the respective seat.
At this point, in addition to Rep. DeGette, 16 other Democratic congressional incumbents must run a serious campaign for renomination. Fewer Republicans face primary challenges, though Texas US Rep. Dan Crenshaw (R-Humble) has already been defeated in the March 3 GOP primary.
