CO-01: Diana DeGette (D) - Central: Denver Solid Democratic. This Denver district is the safest Democratic seat in the state and DeGette is well-entrenched.

CO-02: OPEN Polis (D) - North: Boulder, Ft. Collins Solid Democratic. Polis's bid for governor should be setting off an avalanche of interest in this very liberal Boulder seat, but for now the all-important Democratic primary is in a holding pattern. Former regent and top state regulator Joe Neguse is the nominal frontrunner for now over businessman Ken Toltz and former Boulder Democratic chair Mark Williams. But Shannon Watts, a founder of the gun control group Moms Demand Action, is likely to run and would be a serious candidate.
