No. 01 — Health care • Federal budget

H.R. 1 — the “One Big Beautiful Bill” Act

Passed by Republicans in July 2025, H.R. 1 carries roughly $1 trillion in Medicaid cuts and raises health-care costs for millions of working families — hitting rural hospitals, nursing homes, ACA coverage, and Medicare. Its $4.3 trillion addition to the deficit sets up an estimated $490 billion Medicare cut over the next decade. The full impact was deliberately delayed until after the 2026 midterms.

What support means
  • —Higher health-care costs for millions of working families
  • —A $4.3 trillion increase to the federal deficit
  • —An estimated $490 billion cut to Medicare
No. 02 — Voting rights

The SAVE Act

The Safeguard American Voter Eligibility Act would force citizens to present a passport or birth certificate, in person, just to register to vote. Millions of eligible Americans can’t easily do that — including 69 million married women whose name doesn’t match their birth certificate and 140 million people with no passport. There is no evidence of the fraud it claims to stop.

What support means
  • —Blocks eligible citizens from exercising their right to vote
  • —Falls hardest on women, voters of color, military serving abroad, and trans citizens
No. 03 — War powers • Foreign policy

War Powers Resolution — Iran

In February 2026 the President partnered with Israel to launch major combat operations in Iran with no congressional authorization, pulling several nations into armed conflict. The Constitution gives Congress — not the President — the sole power to declare war. On July 23, the House passed H.Con.Res. 89 to direct an end to unauthorized U.S. hostilities involving Iran.

What support means
  • —Returns the power to declare war to Congress, as the Constitution requires
  • —Limits the President’s ability to wage an unauthorized war in Iran

How to read these numbers • sources & methodology

Total receipts

Displayed funding-source shares use total campaign receipts reported to the FEC for the 2023–2024 cycle.

The $200 convention

We use $200 as the directional cutoff because the FEC requires contributions over $200 to be itemized. It describes transaction size, not a donor's identity or cumulative cycle giving.

Funding mix comparison

The editorial note first flags candidate contributions and candidate-origin loans when they total at least $500,000 and rank in the top 5% of House campaigns by raw candidate-financing amount. Campaign income such as interest and dividends is excluded from this test. Otherwise, the note compares the balance between small-dollar-sized giving and larger individual and committee giving; that comparison is omitted when those two buckets do not make up a majority of the campaign's receipts.

Most money

From which industries or interest groups did the representative receive the most campaign dollars?

Unusually high

We compare how much money the representative received that is associated with a given interest group with how much other House members received.

Materiality guardrail

Unusually high interests must account for at least $10,000 and 0.5% of total campaign receipts.

Candidate financing & campaign income

Candidate contributions and candidate loans appear with identified campaign income, including bank interest, dividends, and investment income.

Recount and neutral receipts

Recount-related donations follow the same individual/committee and $200 logic as ordinary contributions. Refunds, rebates, offsets, other loans, and unresolved miscellaneous receipts remain in the neutral excluded/misc category.

OpenSecrets-associated dollars

OpenSecrets interest amounts remain on their published basis and are not scaled to match FEC receipts. Association identifies a financial relationship in OpenSecrets classifications; it does not establish causation.
