AIPAC money

None on record

No donations from AIPAC and no AIPAC-paid ads for or against Mark DeSaulnier in FEC filings for the 2022, 2024 or 2026 elections.

AIPAC is a pro-Israel lobbying group that spends on elections two ways. Its PAC collects donations from members and sends them to campaigns, where they become the candidate’s money to spend. Its super PAC, United Democracy Project, runs its own ads, and the candidate gets no say in those, whether they help or hurt.
