Deep Look

Colorado Democrats Prepare for High-Stakes Primary Battles

Colorado Democrats head into Tuesday’s primary elections confronting growing uncertainty as several veteran officeholders face stronger-than-expected challenges from candidates running against the party establishment.

The races have attracted national attention following a string of progressive victories in Democratic primaries around the country, raising questions about whether Colorado could experience a similar political shift.

At the center of the spotlight are U.S. Sen. Michael Bennet, who is seeking the Democratic nomination for governor, and longtime U.S. Rep. Diana DeGette, who is defending her congressional seat after nearly three decades in office.

Bennet Faces Tight Governor’s Race

Bennet entered the race as one of Colorado’s best-known Democrats, but recent polling has suggested a far more competitive contest against Attorney General Phil Weiser than many expected.

Several Democratic strategists familiar with the campaign say internal surveys have shown a narrowing race, reflecting voter frustration with Washington and growing demand for candidates viewed as outsiders.

One Democratic strategist close to the governor’s race said:

“There may be only a slight Bennet advantage at this point,”

adding that private polling has been

“all over the place.”

Weiser has attempted to portray himself as the anti-establishment alternative despite serving eight years as attorney general.

His campaign argues:

“Coloradans trust Phil’s people-powered campaign — not Michael Bennet’s establishment, Washington-style campaign backed by out-of-state billionaires, corporations, and special interests.”

Bennet’s campaign counters that he represents meaningful change based on his governing record.

Campaign spokesperson Jordan Fuja said:

“Michael has a track record of rejecting the status quo and delivering real results for Coloradans — and that’s exactly why he’s running for Governor.”

Fuja added:

“As we close out this campaign, the difference between the candidates couldn’t be more clear: Michael’s offering a vision for a bolder, stronger Colorado and his opponent is relying on the same, tired politics-as-usual.”

DeGette Faces Strongest Challenge in Decades

Representative Diana DeGette is also confronting what many Democrats consider the most competitive primary of her congressional career.

Her challenger, 29-year-old democratic socialist Melat Kiros, has built an energetic grassroots campaign centered on younger voters and progressive activists.

According to political strategists familiar with the race, recent internal polling has tightened significantly, prompting concern among DeGette’s allies and a late influx of financial support from national Democratic organizations.

One Colorado Democratic strategist familiar with the polling said:

“It’s not looking great.”

The strategist added:

“It’s very tough when you’re fighting against a wave.”

Outside organizations have spent roughly $3 million during the campaign’s final month, with most of that funding supporting DeGette or opposing Kiros.

Progressive Organizing Gains Momentum

Kiros’ campaign says it has experienced increased volunteer activity and fundraising following progressive victories in recent Democratic primaries elsewhere in the country.

She told reporters:

“We feel very confident that the program that we’ve built, the movement that we’ve built, is going to be able to combat any amount of money that they throw at us in this final week.”

She added:

“This is the people organizing and making it abundantly clear that they are no longer accepting the status quo and are demanding the change.”

Her campaign says more than 5,000 volunteers have participated in organizing efforts, while local Democratic Socialists of America chapters and national progressive organizations have expanded phone banking and canvassing operations across Denver.

Popular online political commentator Hasan Piker has also announced plans to assist with organizing efforts leading up to Election Day.

Colorado’s Political Landscape May Differ

Despite growing progressive enthusiasm, several Democratic strategists caution that Colorado’s political environment differs from cities such as New York.

Denver’s Democratic electorate is generally viewed as less ideologically left-leaning, and longtime incumbents still benefit from strong name recognition and established political relationships.

Nevertheless, many party insiders acknowledge that the city’s younger electorate has become increasingly receptive to anti-establishment candidates.

One Democratic strategist close to DeGette’s campaign said:

“Everybody now knows this is a race. This is no longer sneaking up on everybody.”

The strategist added:

“I think DeGette should be very concerned.”

Election Could Reshape Colorado Democrats

Longtime Democratic strategist Doug Friednash believes voter frustration remains one of the defining forces in this year’s primaries.

“There’s a lot of anti-establishment momentum because voters are so angry,” he said.

“They want to take it out on someone. They want fighters.”

While Friednash believes DeGette still has a path to victory, he says an upset would dramatically reshape the state’s political landscape.

“That’s a massive game changer in Colorado politics.”

Tuesday’s results will determine whether Colorado joins the growing list of states where progressive challengers have successfully unseated established Democratic leaders, potentially signaling a broader shift inside the party heading toward the 2026 general election.
