Incumbent Republican Lauren Boebert holds a clear edge in Colorado’s 4th Congressional District, a solidly Republican seat where Donald Trump won by double digits in 2024 and prior GOP margins exceeded 12 points. Both candidates advanced from their June 30, 2026 primaries—Boebert unopposed and Democrat Eileen Laubacher defeating a write-in—setting up the November 3 general election. Laubacher, a retired Navy rear admiral, has outraised Boebert by a wide margin, exceeding $10 million with millions in cash on hand, and launched her first television ads in early September emphasizing moderation and constituent focus. These factors sustain some Democratic competitiveness in trader pricing, yet the district’s partisan composition and Boebert’s incumbency continue to anchor the market consensus.
