Primary
Polling suggests that today’s Colorado Democratic gubernatorial primary could produce another major upset. Surveys indicate a surprisingly close contest between Sen. Michael Bennet and Attorney General Phil Weiser.
When Sen. Bennet entered the Governor’s race – without having to risk his Senate seat – several competitive candidates withdrew, assuming he would be difficult to defeat in a statewide primary. The one officeholder who remained was term‑limited Attorney General Weiser, and current polling indicates that Sen. Bennet losing tonight is a realistic possibility.
Recent primary and runoff polling around the country has been inconsistent. For example, a Wedgewood Polls survey of the Louisiana Republican Senate runoff (June 22-24; 753 likely Louisiana GOP voters) showed State Treasurer John Fleming leading Rep. Julia Letlow 51-47 percent. On June 27, however, Letlow won 57-43 percent. This underscores the need for caution when interpreting public polling.
The most recent study, from reputable Public Policy Polling (June 24-26; 600 likely Colorado Democratic primary voters; text & live interview) projects AG Weiser to be leading Sen. Bennet 45-36% percent. In PPP’s June 1-2 poll, Sen. Bennet was ahead 36-30 percent.
A further challenge for Bennet is that his support appears to have a ceiling. After beginning the year with a 2:1 lead over any prospective Democratic opponent, including Weiser, Sen. Bennet has not exceeded 36 percent in any poll – a clear warning sign for his prospects tonight.
Even if Bennet loses, it would be difficult to frame the result as a Democratic Socialist victory, however. While Weiser is campaigning to the left, he is not relying upon socialist rhetoric. Like all Democratic candidates, he is running against President Trump, but he has also emphasized Colorado‑specific issues and mounted an exhaustive campaign effort. If Bennet assumed Weiser would be easy to defeat, he appears to have misjudged his opponent.
In the Senate race, incumbent and former Gov. John Hickenlooper should win renomination tonight, but even he has not performed particularly well in the one recent poll we have seen of this race. Expect Sen. Hickenlooper to defeat state Sen. Julie Gonzalez (D-Denver), another DSA candidate, but his victory percentage may be smaller than one would expect from a well-known incumbent before voters of his own party.
Several House races are also contested, but Reps. Joe Neguse (D-Lafayette/Boulder), Lauren Boebert (R-Silt), Jeff Crank (R-Colorado Springs), Jason Crow (D-Aurora), and Brittany Petersen (D-Lakewood) are all unopposed for renomination.
One of the most striking contests is the DSA challenge to veteran Rep. Diana DeGette (D) in Denver’s 1st District. Attorney Melat Kiros is running slightly ahead in limited polling and dominated the Democratic endorsing convention. Kiros received nearly 70 percent support from convention delegates, while DeGette qualified for the ballot by only eight delegate votes above the minimum – making this another potential DSA upset.
In the western slope 3rd District, freshman Rep. Jeff Hurd (R‑Grand Junction) faces a primary challenge from former state Rep. Ron Hanks. Rep. Hurd is expected to win easily but will likely face a competitive general election, probably against venture capitalist Alex Kelloff.
The 8th Congressional District, located north and northeast of Denver, was created by the Colorado Independent Redistricting Commission as a domain that the local political winds could influence. CO-8 is one of the most politically marginal districts in the country, and every election is expected to be competitive.
Democrats began with a large primary field, but most candidates have withdrawn, realistically leaving a contest between state Rep. Manny Rutinel (D‑Commerce City) and former state Rep. Shannon Bird. Rutinel has been a strong fundraiser but spent heavily during the primary. Ms. Bird, viewed as a slight underdog, is the more centrist candidate and has faced outside attacks for being too pro‑Israel. The stakes in this primary are high.
The winner will face freshman Republican Gabe Evans (R‑Ft. Lupton/Thornton), who is considered one of the most endangered GOP incumbents in the nation due to the district’s competitiveness. Regardless of tonight’s Democratic outcome, the CO‑8 general election will immediately become a national congressional contest.
