Colorado’s longest-serving House member, Rep. Diana DeGette, is suddenly in the toughest primary of her career, with a 28-year-old progressive and a University of Colorado regent both muscling their way onto the June ballot. An upset in this safely blue Denver seat still looks like a long shot, but a surprise delegate result and a competing petition drive have turned a sleepy renomination into a real fight. The June 30 Democratic primary will test whether seniority or a fresh face sets the pace in Denver’s 1st Congressional District.
Delegate shock at the assembly
At the March 27 district assembly, newcomer Melat Kiros stunned the room by sweeping the delegate preference while DeGette barely cleared the 30 percent threshold she needed to stay on the ballot. That outcome put Kiros in the coveted top line on the primary ballot and left DeGette just a handful of votes from being knocked out entirely, as reported by Westword.
What the numbers mean
Kiros secured 157 of 236 delegate votes to DeGette’s 79, giving her roughly two-thirds of the preference vote, according to the Denver Gazette. With DeGette only nine votes away from elimination, the tally signaled a clear appetite for change among Denver party insiders. Still, assemblies are just one path to the ballot; candidates can also qualify through petition drives that bypass the delegate crowd and go straight to rank-and-file voters.
Wanda James petitions onto the ballot
University of Colorado regent Wanda James chose that alternative route. She filed petition signatures with the Secretary of State on March 18 to try to secure a spot on the primary ballot, a move recorded on the state’s list of petition candidates on the Colorado Secretary of State site. James, who owns the Simply Pure dispensary and won election to the CU Board of Regents in 2022, has laid out priorities that include protecting voting rights and expanding child tax credits. Colorado Public Radio has detailed her background and some of the controversies that have followed her into this race.
Money and reach
On the money front, DeGette is still the heavyweight. Federal Election Commission records show her campaign reported about $713,394 in receipts for 2025. Melat Kiros’s committee reported roughly $204,542 in that same period, according to the FEC, while trackers put Wanda James’s 2025 fundraising near $179,530. That cash gap gives DeGette a clear organizational advantage as the campaigns shift from inside-baseball assembly politics to a districtwide vote. With television time and field staff not coming cheap, those extra dollars can translate into more mail, more calls, and more doors knocked before June.
A steep hill, but not impossible
History is on DeGette’s side. Incumbent losses in Colorado congressional primaries are extremely rare; Westword notes a 9News analysis finding that no Democratic member of Congress in the state has lost a primary in more than 50 years, and that Lauren Boebert is the only challenger this century to unseat a Colorado incumbent. At the same time, party assemblies have not always predicted how the broader electorate will vote. Turnout and voter contact will decide who actually lands the nomination. The next six weeks will show whether Kiros’s surge among delegates or James’s petition play can be turned into real votes in precincts across Denver.
What to watch next
Mail ballots are set to go out in early June and must reach county clerks by 7 p.m. on June 30, setting a tight window for ground operations, according to the Denver Gazette. DeGette has already started spending on the airwaves, debuting a television ad on April 14 that reminds voters of her three decades in office, a sign the veteran lawmaker is treating the challenge as serious business, per Axios Denver. From here, the contest is likely to turn on who can get their voters actually to return those ballots, how well each campaign targets its outreach, and which message can keep momentum going all the way to the finish line.
