For decades, the American Israel Public Affairs Committee had been an influential presence on Capitol Hill, working behind the scenes to lobby politicians and their staffers in support of Israel. But ahead of the 2022 midterm elections, AIPAC made a decision that would fundamentally alter its purpose and the contours of American politics.

After 60 years of issues-based lobbying, AIPAC for the first time opted to spend directly on campaigns. Flush with millions of dollars from loyal donors, among them Republican billionaires and megadonors to former President Donald Trump, AIPAC embraced a new strategy. It would use its vast funds to oust progressive members of Congress who have criticized human rights abuses by Israel and the country’s receipt of billions of U.S. dollars in military funding.

Just two years after it started pouring money into campaigns, AIPAC has become one of the largest outside spenders in congressional elections. The Intercept has chronicled AIPAC’s power through coverage of individual races, but never before has AIPAC’s massive outflow of money been analyzed in sum. This project uses records from the Federal Election Commission — submitted by the lobbying group’s federal political action committee, AIPAC PAC, and its super PAC, United Democracy Project — to map how much money has been spent on behalf of Israel, where these groups are doling out money, and what impact those funds are having on the balance of power in Congress.
