Limits of this data

Candidate totals come from each campaign's most recent filed report; most cover through June 30 or September 30, so recent fundraising is not yet visible.

Outside spending is reported within 24–48 hours near elections, so it is far more current than candidate totals.

2026 figures are filings to date; past midterms are complete cycles.
