An ad counts for the state only when its targeting named no other; Google’s state split is cumulative since 2018 and is not used. Spend is a sum of Google’s per-ad ranges; a side comes from the advertiser’s FEC committee, or failing that from a web search of its verified name. No ad text is published, so Google ads are not placed in races.
A state’s page counts ads about its races and measures; the state comes from the ad’s text, page and payer, or the candidate’s FEC record. Ads about no single state are not here. Candidates are those whose FEC committees paid; state and local candidates appear through their pages.
