Today's Colorado Primaries Could Impact The Midterm Elections Nationwide

Colorado Democrats vote Tuesday in primaries that could hand Republicans their most useful campaign weapon of the 2026 midterms: proof that the socialist wave crashing through New York City was never just a New York problem.

Three weeks ago, the Democratic Socialists of America notched a trio of wins in New York City that sent establishment Democrats into a panic. Darializa Avila Chevalier knocked off Rep. Adriano Espaillat, chairman of the Congressional Hispanic Caucus, in the 13th District on a platform that included shutting down prisons, eliminating ICE, erasing the southern border, and opposing the deportation of illegal immigrants regardless of criminal record. Claire Valdez took the 7th District running on citizenship and voting rights for people who entered the country illegally, taxpayer-funded transgender medical treatment, and the elimination of private health insurance. Brad Lander won in the 10th District by nearly 30 points, defeating Rep. Dan Goldman, one of the most prominent anti-Trump voices in the caucus and the man who led the push to impeach the president.

Colorado now gets to answer the question everyone in Washington has been asking since New York's results came in: was that a fluke confined to one deep-blue city, or the opening act of something bigger? Sen. Michael Bennet and Rep. Diana DeGette, two of the biggest names in Colorado Democratic politics, both face primary challenges that party insiders are taking far more seriously than they expected to a month ago.

CNN's Harry Enten warned Democrats about the implications last week after the New York primaries. "What is true in New York City in a Democratic primary ain't necessarily true nationwide with the general electorate," Enten said last week. The Democratic Socialists of America have a net favorable rating of +17 among Democrats and Democratic-leaning independents, according to Enten's data, but are 27 points underwater with the electorate as a whole. That 44-point canyon between the party's base and everyone else is precisely the gap Republicans intend to exploit. "Socialism has become increasingly popular among Democrats, but it is a much tougher sell in the rest of the electorate," Enten said. Favorable views of socialism among Democrats climbed from 50% in 2010 to 66% today. Among everyone else, the number has barely moved, sitting at 30% now versus 29% sixteen years ago.

Polls show socialism is on the rise in the Democrat party but still highly unpopular amongst the overwhelmingly majority of Americans.

Bennet abandoned his Senate seat to run for governor and now finds himself locked in a tighter-than-expected race against Attorney General Phil Weiser. A poll from the left-leaning firm PPP also showed Bennet trailing Weiser outside the margin of error, and two Democratic strategists familiar with the campaign said internal numbers track the same direction. "There may be only a slight Bennet advantage at this point," said a Democratic strategist close to the race, granted anonymity to speak candidly, who described private polling as "all over the place." Weiser, despite having eight years' experience running the attorney general's office, has somehow managed to cast himself as the outsider, branding Bennet a creature of Washington. Strategists say the message is sticking with primary voters who want nothing to do with anyone who smells like the establishment this cycle.

DeGette's situation looks worse. After serving three decades in the House, she faces democratic socialist Melat Kiros. Internal polling has tightened to within the margin of error, and donors who dismissed the threat for weeks are suddenly paying attention. "It's not looking great," said one Colorado Democratic strategist familiar with DeGette's numbers. "It's very tough when you're fighting against a wave." DeGette rolled out a last-minute endorsement video from Rep. Pramila Jayapal (D-Wash.), former chair of the Congressional Progressive Caucus. This move backfired with some progressives, given that Kiros already has Sen. Bernie Sanders in her corner.

Sen. John Hickenlooper is fending off his own challenge from state Sen. Julie Gonzales, with a private survey showing a dead heat in Denver even as a late-May public poll had Hickenlooper ahead 41% to 34% amid heavy undecideds. National DSA chapters have run phone banks for Kiros nearly daily, and Denver organizers expect close to 100,000 doors knocked by the time polls close.

"There's a lot of anti-establishment momentum because voters are so angry," Doug Friednash, a longtime Colorado Democratic strategist, said. "They want to take it out on someone. They want fighters." Denver isn't New York, and Democrats note that the city's DSA infrastructure remains smaller, and that DeGette's name recognition runs deeper than Espaillat's ever did. But Denver has also grown younger and more restless, and that combination worries establishment Democrats.

Republicans are watching with open delight. "That's what the left is putting out. It's these radical leftists that are being elected. They're being inspired by Mamdani, AOC, Bernie Sanders," RNC Chairman Joe Gruters told Newsmax, adding that the trend hands the GOP favorable matchups in competitive districts nationwide. "The people are going to reject this at the polls," Gruters said, betting that a party drifting this far left has wandered clean off the map most American voters still occupy.

If Colorado follows New York's lead, Democrats won't just be arguing about ideology inside their own party, they'll be handing Republicans a ready-made message for the 2026 midterms that the Democratic Party as a whole has become too radical for mainstream America.
