Zoom in: Spending backing U.S. Rep. Yadira Caraveo, a Democrat, reached $16.7 million in Colorado's 8th Congressional District race.
That total dwarfs the $9.5 million raised for her Republican challenger, state Rep. Gabe Evans, to take the suburban Denver seat.
Meanwhile, House Minority Leader Hakeem Jeffries (D-N.Y) and his allies are outspending Republicans in nine of the 10 most expensive House races of the cycle.
Between the lines: The spending figures include money used by candidates, parties and super PACs.
Threat level: The fundraising totals cement fears among House GOP leaders that the party is outgunned as it tries to maintain its majority.
The bottom line: Democrats are spending double what Republicans are on political ads in Colorado, giving them a significant advantage heading into the final weeks before the Nov. 5 election.
