Sorted by total money deployed (outside money benefiting either candidate + both campaigns' cycle-to-date spending). "Outside, benefiting" = independent expenditures supporting the candidate + those opposing the opponent, general-election window only. Candidates are listed Republican first, then the other principal candidate; see each race page for third candidates.
Campaign spending is each principal campaign committee's cycle-to-date total disbursements from the FEC candidate summary file (it includes primary-season spending; the outside-money columns do not). Where a race's page lists a scope caveat — a top-four general, a third funded candidate, a special election — the same caveat applies to its row here.

2 How these pages are built
Every race page is produced by one shared pipeline from the FEC's bulk files (independent expenditures, candidate and committee summaries, committee-to-candidate contributions, operating expenditures, individual contributions) and the committees' own filings on FEC docquery. The method is identical for every district, and the same as for the Senate race pages; each race page documents it section by section in its own footnotes (§7.1–§7.15), and the methodology page covers the sources and the attribution rule. No figure on any of these pages comes from an estimate.
