Receipts, cash on hand, and outside (independent-expenditure) spending from the Federal Election Commission. Bars are scaled within this race. Both party primaries are June 30, 2026 (NOT yet held as of June 25). Incumbent John Hickenlooper (D) is the heavy frontrunner over progressive state Sen. Julie Gonzales (D) in a contested primary. State Sen. Mark Baisley is running unopposed in the GOP primary (cleared field, presumptive nominee). Minor general-election filers not yet confirmed on the ballot. The field and its fundraising will keep updating as primaries settle and new FEC reports land.
The rating is grounded in this seat’s record on Akashic — its partisan lean, same-office history, and demographics. Read the full profile on the CO state page.
