Candidate money and outside spending have different reporting cutoffs. Where available, outside totals cover the full election cycle, including primaries; recent spending may be absent.

Money sources and coverage

FEC bulk candidate summaries through October 14, 2026. Candidate summaries may include earlier election stages. A dash or unavailable record does not establish that no outside spending occurred. Do not add outside spending to candidate receipts: money spent independently is separate from money raised by the candidate. These tables do not estimate a causal effect on votes; the race's model explanation identifies the inputs it actually uses. Outside spending covers 2025–2026, including spending during primaries. Records retrieved October 31, 2026, 16:02 UTC. These FEC figures include processed regular filings, not separate 24/48-hour notices; recent spending may be absent. Some filings submitted before the retrieval time may still be missing. Spending is matched by FEC candidate ID to the candidates listed here.

Outside spending by committee

FEC processed records for 2025–2026, retrieved October 31, 2026, 16:02 UTC. These amounts pool election stages, including primaries; they are not November-only totals. Support and opposition refer to the named candidate. Recent spending may be absent.

Sources, coverage and accounting

Unclassified records remain separate. These FEC committee and candidate totals use the latest processed amended regular filings, exclude Schedule E memo entries and include Form 5/7 spending under FEC processing rules. Separate 24/48-hour notices are not added. Recent spending reported only in notices may be absent. Retrieval time is not a guarantee that all filings through that time were processed. Committee sums reconcile to FEC candidate totals. Negative amounts reflect net adjustments. Only candidates with outside-spending records appear below; candidate receipts and outside spending have different reporting cutoffs. Record counts are expenditure entries, not unique filings.
