The widest one reaches

24states

Independent spending filed on Colorado's races, by whether the committee is also spending in other states this cycle. A filing records where a group spends, not where its donors live, so this is a measure of reach, never of who paid for it.

Every race on the ballot

Candidates on file with the FEC, not a certified ballot. Each row opens the full field, the money, and the outside spending for that seat.
