Once Sen. Bennet declared his gubernatorial candidacy, all but one of the major prospective Democratic contenders abandoned their ambitions – choosing instead to seek re‑election, pursue other statewide offices, or exit electoral politics altogether. The lone holdout was Attorney General Phil Weiser, who is term‑limited and therefore unable to seek a third term. He remained in the race as Sen. Bennet’s only significant primary opponent.
It is now clear that Weiser has become a serious threat. At least one recent survey has even shown him leading the primary. Two of the latest publicly released polls illustrate the tightening contest: Public Policy Polling (June 1-2; 505 likely Democratic primary voters; text and live interview) found Bennet ahead 36-30 percent, while Colorado Community Research (May 22-28; 796 likely Democratic primary voters) showed Weiser leading 41-34 percent.
Neither poll is encouraging for Bennet. Even in the PPP survey, where he holds a narrow lead, the fact that a four‑term US Senator (appointed in 2009 to replace Ken Salazar and subsequently elected in 2010, 2016, and 2022) is polling only in the 30s among his own party’s primary electorate as the early voting period begins is hardly a sign of political strength.
Several of Bennet’s strategic decisions, combined with an unexpectedly vigorous grassroots effort from Weiser, have contributed to the competitiveness of the race.
The Senator’s first questionable move was bypassing the state party’s nomination assembly. Colorado candidates can access the primary ballot in one of two ways: by securing at least 30 percent of the delegate vote at the state endorsing convention, or collecting the required number of petition signatures – 1,500 from registered party members in each of the state’s eight congressional districts. Candidates may pursue both paths simultaneously as a safeguard. Sen. Bennet chose to skip the assembly entirely and rely solely on petition signatures.
Weiser, by contrast, attended the assembly and surpassed the 30 percent threshold, earning his ballot line. Sen. Bennet’s decision raised eyebrows, suggesting either a lack of confidence in his ability to win over party delegates or a desire to avoid the rigors of the convention process altogether.
A second misstep came when Bennet stated that, if elected Governor, he intended to remain in the Senate long enough to choose his own successor rather than resign immediately and allow outgoing Gov. Jared Polis (D) to make the appointment. Critics quickly seized on the remark, accusing Bennet of attempting to consolidate too much power.
Meanwhile, Weiser’s campaign has been more aggressive and effective than many anticipated. In his campaign appearances around the state, he has criticized Bennet – and DC Democrats more broadly – for not applying sufficient pressure on President Trump. He contrasts this with his own record, highlighting the 65 lawsuits he has filed or enjoined against the Trump Administration.
There is little doubt that the winner of the June 30 Democratic primary will be strongly positioned to become Colorado’s next Governor, given the state’s continued leftward shift. Sen. Bennet may ultimately secure the gubernatorial nomination, but if he does, the victory will likely be viewed as far less impressive than many expected when he first announced his return to state politics in early 2025.
Moreover, federal incumbents seeking different offices in the 2026 cycle have not fared well in either party. Base party primary voters have shown frustration with Washington, rejecting several sitting members of Congress in their bids for Senate seats or gubernatorial positions. Sen. Bennet’s status as a long‑time federal officeholder may be yet another factor weighing down his current campaign.
