**The CO-04 House race remains anchored by the district’s strong Republican lean, where incumbent Lauren Boebert won by nearly 12 points in 2024 and rating services classify it as solid or likely Republican.** Recent polling from late September showed Boebert ahead 45-40 percent, though with negative job approval and a Libertarian candidate drawing 9 percent. Laubacher’s substantial fundraising edge—over $3.6 million cash on hand versus Boebert’s roughly $247,000—has narrowed the gap in surveys but has not overcome the underlying partisan math. An ethics complaint filed in September alleging improper relationships with staffers drew denials from Boebert and was timed close to the November 3 ballot, yet trader pricing continues to price in her incumbency advantage in the most Republican-leaning Colorado district.
