FEC candidate committee totals for the 2026 cycle, through October 14, 2026. Outside for / against is Schedule E independent spending by other committees to support or oppose the candidate. Each figure links to the candidate's FEC page.

Platform ad spend

Meta's Ad Library Report, Google's Ads Transparency Center and Snap's political-ads library. An advertiser is tied to a candidate only when its name carries the candidate's surname together with this state or the candidate's full name; outside groups that do not name a candidate appear in the state and district totals, not here.

No advertiser on either platform names a candidate in this race.

Meta in Colorado: $1.9M Oct 25, 2026 - Oct 31, 2026 · Google in Colorado: $62.0M lifetime · Snap targeted at Colorado: $104k in 2026.
