Colorado Politics: Redistricting and national trends threaten GOP hold on key seats
Cook Political Report downgrades Lauren Boebert's district from Solid R to Lean R, while other Republican-held congressional races in the state face increased Democratic spending and polling shifts.

The Republican Party's grip on four congressional districts in Colorado faces a test as national polling suggests a strong Democratic turnout. Analysts have downgraded several races that were considered safe for years, driven by shifting voter dynamics and heavy campaign spending.
The most striking shift involves the 4th Congressional District, currently held by Rep. Lauren Boebert. The Cook Political Report moved the district from a Solid Republican rating to Lean Republican, skipping the Likely Republican tier. Larry Sabato’s Crystal Ball issued a similar downgrade. This change is notable because the district voted for Donald Trump by 18 points in the 2026 election.
Cook cited specific campaign factors for the downgrade. The report noted that Boebert left $6 million worth of attack ads unanswered. New polling data indicates the race is closer than the district’s historical voting patterns would suggest. Boebert has raised slightly more than $1 million for her campaign. Her Democratic challenger, retired Rear Admiral Eileen Laubacher, has raised more than $13 million.
The 5th Congressional District, a Republican stronghold for decades, is now rated a tossup by ranking organizations. Democrat Jessica Killin is challenging incumbent Jeff Crank. Crank won the district by 14 points in 2024. Killin previously served as chief of staff for three members of the U.S. House and for Vice President Kamala Harris’s spouse, Doug Emhoff. Harris lost the district by 10 points in 2024.
In the 8th Congressional District, the race between Republican incumbent Gabe Evans and Democrat Manny Rutinel is rated Lean Democrat. This assessment has been in place since the summer primaries. The district was drawn in 2022 by the redistricting commission, a process that shifted the political balance in the state’s congressional map.
Democrats have increased financial support for challengers in other Republican-held seats. In the 3rd Congressional District, Democratic candidate Dwayne Romero received $2.1 million in recent fundraising. The race is rated Likely Republican, with incumbent Jeff Hurd holding the seat. Romero is a West Point graduate and Army Ranger.
The Cook Political Report maintains a high accuracy rate in predicting election outcomes. An internal review reported by the Washington Post found that its Likely ratings were correct in 97% of 10,375 called races since 1984. Its Lean ratings were correct in 94% of those contests.
Colorado’s political landscape has shifted significantly over the last decade. Republicans hold no statewide offices and have elected only one governor in more than 50 years. The state House and Senate are overwhelmingly Democratic. The party currently holds an even 4-4 split in the U.S. House delegation from Colorado.
The current election cycle features unusual national conditions. Trump’s approval ratings are at record lows, and polling suggests a potential Democratic majority in both chambers of Congress. Nate Silver’s models place the Democrats at a 94.7% probability of winning the House and a 78.3% probability of winning the Senate. These national trends are influencing state-level races in Colorado.
