Does pro-Israel campaign money (from AIPAC-aligned PACs, DMFI, and pro-Israel super PACs) track how members of Congress vote on Israel and Palestine? This insight places each member's FEC-reported Israel/Palestine campaign finance next to their weighted voting and sponsorship record, so you can see the relationship between money and votes across the House and Senate. The relationship shown is correlational, not causal.

Across 539 current members of Congress, 502 have received pro-Israel money (PAC direct and independent support, curated network donors, and earmarked contributions bundled through pro-Israel conduits).
CSV — one row per member: pro-Israel money, vote counts, alignment and dollars-per-vote. Re-bucket and recompute every band yourself.
CSV — the per-tier band counts and percentages exactly as plotted in the dose-response chart above.
Every current member who has cast at least one tracked Israel/Palestine vote is placed into one of five tiers by the total pro-Israel money they’ve received. Each bar shows 100% of the members in that tier, split into three bands by how reliably they vote the pro-Israel position:
Read the bars left to right, from least money to most: the “votes pro-Israel under 50% of the time” band shrinks dramatically as the money rises. That shrinking band is the whole story.
A member’s tier is set by the same pro-Israel money total shown on their own profile page, so the two can never disagree. It is the sum of:
Liberal-Zionist money (J Street and similar) is tracked separately on each profile and is
For readers who want to check the math rather than take our word for it, here is the full specification. The notation matches the downloadable data below, so every band on this page can be reproduced from the raw file.
The scorecard ratio for a member with at least one pro-Israel vote is
It is reported per member, never averaged into the tiers — a blunt descriptive ratio, not a price.
A fair question is whether the dose-response is an artefact of how the bands are drawn or of a handful of members. Each band is a plain count proportion, so its uncertainty is the binomial standard error
The pattern is not just “funded vs. unfunded”: restricting to members who took
Computed within Democrats alone — where essentially all of the under-50% members sit — the gradient is weaker but still present: low-money Democrats break with the line far more often than well-funded ones. Party is the largest confound and we say so plainly below.
The headline — dissent collapses as pro-Israel money rises — survives all three. The exact band heights of the smallest tiers do not, and we don’t lean on them.
Both files reflect the current published snapshot and refresh when the site is rebuilt. The raw file is the source of truth; the computed file is what we plot, provided so you can confirm we transcribed our own output faithfully.
Pro-Israel money concentrates among members already inclined to vote that way, and almost all of the under-50% members are progressive Democrats in safe seats. The money–vote link is real but it is entangled with party and district safety.
Both the money totals and the vote records are a current snapshot; they shift between Congresses and between site rebuilds.
Correlation is not causation. Money flows toward members who were already going to vote a certain way at least as much as it changes anyone’s mind — pro-Israel groups fund reliable allies and spend heavily to defeat opponents in primaries. The chart shows that the money and the votes
