- Colorado has voted Democratic in every presidential election since 2008 and now rates D+5 at the presidential level — making it a reliable Democratic anchor in Senate math.
- Hickenlooper is the favorite in 2026 but not a sure thing: his moderate positioning on energy policy (oil and gas are significant Colorado industries) creates some primary and general tension.
- Colorado's energy policy squeeze is real: Hickenlooper must balance urban/suburban Democratic climate voters against rural oil and gas communities that are economically important to the state.
- Republican recruitment has been the NRSC's persistent challenge in Colorado — the state's suburban evolution has made it difficult to recruit credible candidates who can win both a primary and a general.
- Hickenlooper's ex-governor experience and business background (he founded the Wynkoop Brewery in Denver) give him a centrist profile that outperforms the Democratic baseline in moderate suburban precincts.
Colorado Senate: Presidential and Senate Margins 2014–2026
| Year | Senate Race | Senate Margin | Presidential Cycle | Pres. Margin |
|---|---|---|---|---|
| 2014 | Gardner (R) def. Udall (D) | R+1.9 | Obama 2012 | D+5.4 |
| 2016 | Bennet (D) def. Glenn (R) | D+5.9 | Clinton 2016 | D+4.9 |
| 2020 | Hickenlooper (D) def. Gardner (R) | D+9.3 | Biden 2020 | D+13.5 |
| 2022 | Bennet (D) def. O'Dea (R) | D+11.8 | Biden 2020 | D+13.5 |
| 2026 | Hickenlooper (D) vs. TBD | Projected D+5 to D+9 | Harris 2024 | D+11.4 |
Hickenlooper consistently underperforms the Democratic presidential margin in Colorado. A D+11 presidential state translates to roughly D+6 to D+8 in his Senate race.
The Energy Policy Squeeze
Hickenlooper's Senate record has created a political problem unique to Colorado: he has antagonized both the state's significant oil and gas industry and its large, organized environmental voter base. Colorado is one of the top 10 natural gas-producing states in the nation, with significant drilling operations on the Western Slope and in Weld County. Hickenlooper, a former geologist and oil executive before entering politics, has been more cautious than most Senate Democrats on drilling restrictions, earning him criticism from progressive climate groups. At the same time, he voted for the Inflation Reduction Act and supported clean energy investment, making him a RINO equivalent in the eyes of some energy industry voters.
This squeeze creates a genuine approval rating problem. Hickenlooper has polled in the low-to-mid 40s in Colorado, below what a senator in a D+11 state should expect. His path to re-election runs through Denver-metro college-educated voters who prioritize climate, and he will need to consolidate that base while defending his energy record to Weld County and the Western Slope.
Republican Recruitment: The Missing Piece
A former statewide official who explicitly distances from Trump's 2024 platform could compete in Jefferson and Arapahoe. D wins by D+3 to D+5. Race is genuinely competitive.
Republican wins primary by running right, alienates suburban Denver voters, and Hickenlooper wins by D+6 to D+8. Competitive but not a toss-up.
Hickenlooper wins by D+11 to D+13, matching presidential margin. Happens if national environment swings sharply against Republicans mid-term.
Bottom Line: Hickenlooper is the Favorite, Not a Sure Thing
Colorado's structural tilt toward Democrats, combined with Hickenlooper's incumbency and fundraising advantages, makes him the clear favorite to win re-election. But his approval deficit, the energy policy vulnerability, and Colorado's history of producing genuinely competitive Senate majority math maths (2014 was R+1.9) keep this in the Lean D rather than Likely D category. The outcome depends heavily on Republican candidate quality. If the GOP primary produces a candidate who can appeal to Denver-metro moderates without endorsing the full 2025 Trump policy agenda, this race will be competitive. If it produces another Weld-County-base candidate with MAGA branding, Hickenlooper wins comfortably. Rating: Lean D.
