Incumbent Jeff Hurd maintains a commanding lead in trader consensus for the Colorado 3rd Congressional District Republican primary due to President Trump's restored endorsement in March 2026 after briefly backing and then withdrawing support from former state party official Hope Scheppelman. Scheppelman's subsequent campaign suspension to join the Trump administration removed the most visible challenge, while Hurd's substantial fundraising advantage and prior primary performance further consolidated support ahead of the June 30 primary. Remaining opposition from candidates such as Ron Hanks has not shifted probabilities. A late surge by an alternative contender or unexpected procedural development could still alter the outcome before ballots close.
