Colorado's Democratic primaries on Tuesday will help answer a question the party has increasingly faced nationally: Are voters gravitating toward a younger, more progressive generation of leaders or sticking with established veterans? That choice is starkly reflected in multiple competitive races across the state.
In the state's 1st Congressional District, incumbent Rep. Diana DeGette has been in office for nearly three decades. Her challenger, Melat Kiros, a 29-year-old democratic socialist, was born the year DeGette first took office. At a March Democratic assembly to decide which candidates qualify for the primary ballot, Kiros received more than double the votes of DeGette, though the assembly process is not determinative of Tuesday's outcome.
What the Right Is Saying
DeGette argues that experience in Congress is exactly what's needed right now to combat Trump and protect Democratic priorities. She has the backing of Colorado's established Democratic House delegation, who argue institutional knowledge matters when negotiating with a Republican-controlled government.
Hickenlooper remains favored in the Senate race. Supporters point to his record as former governor and say his pragmatic approach has delivered results for Colorado. They question whether more progressive challengers can win statewide in November against Republican opponents.
In the governor's race, Phil Weiser has attacked Michael Bennet for voting for some Trump nominees, while Bennet has criticized Weiser for not joining state lawsuits against Trump's first administration. The two Democrats have struggled to show major policy differences and instead have focused on debating each other's records.
What the Left Is Saying
Kiros has received the endorsement of Sen. Bernie Sanders, who has championed progressive challengers to establishment Democrats across the country. Supporters argue that new voices are needed to combat President Donald Trump's agenda more aggressively. Kiros, a former attorney, accuses DeGette of ineffectiveness in Congress despite her long tenure.
State Sen. Julie Gonzales, who describes herself as an 'insurgent progressive,' is challenging Sen. John Hickenlooper for the U.S. Senate seat. She's embraced arguments used by other progressive challengers, calling Hickenlooper an 'incrementalist' and arguing that bolder action is needed. Gonzales has said she previously joined the Democratic Socialists of America in 2018, though her membership has since lapsed.
In Colorado's 8th Congressional District, a swing seat that could determine control of the House, state Rep. Manny Rutinel argues his personal background and more aggressive economic agenda will be more effective against Republican Rep. Gabe Evans than his primary opponent's approach. The district is heavily Hispanic and has swung between parties since its creation in 2021.
What the Numbers Show
The March assembly results showed Kiros with more than double DeGette's delegate support, though incumbents often perform better in actual primaries than assemblies. Two democratic socialists and a progressive defeated establishment-backed candidates, including two incumbents, in New York Democratic primaries last week, energizing the movement nationally.
Colorado is a reliably blue state, meaning Tuesday's Democratic winners will be heavily favored in November against Republican opponents. The 8th Congressional District represents one of fewer than two dozen seats that could determine House control. President Trump is in his final two years in office with Republicans seeking to maintain their majority.
The Bottom Line
Tuesday's results will test whether the progressive insurgent wave that succeeded in New York can translate to Colorado, where longtime incumbents have built deep party infrastructure. Even if DeGette and Hickenlooper win their primaries, narrow margins would signal voter appetite for a generational shift within the Democratic Party ahead of future elections.
The governor's race is notable because both candidates are Democrats with similar platforms in a state that will almost certainly remain blue regardless of Tuesday's outcome. The real contest will be November against whichever Republican emerges from a field that includes far-right state Rep. Scott Bottoms and more conventional Republican state Sen. Barbara Kirkmeyer.
