VoteLog discovers bills by searching Congress.gov for Israel/Palestine-related keywords, then classifies each as pro-Israel, pro-Palestine, neutral, or a bundled package. Each member's weighted score adds 3 points for sponsoring, 2 for cosponsoring, and 1 for a supportive roll-call vote, signed by the bill's classification.
Campaign-finance figures come from the FEC: committee-level direct contributions (Schedule B) and independent expenditures (Schedule E) from a curated registry of Israel/Palestine-aligned PACs and super PACs. These totals are a documented lower bound — bundled individual donations are not fully captured.
