It’s a bit of obfuscation and I’m not sure it’s a really relevant distinction even if it is factually correct. AIPAC is essentially a colloquialism for the Israel lobby at this point and that’s why the research focuses on AIPAC adjacent donations instead of AIPAC itself. AIPAC is a Public Affairs Committee that acts more as a traffic director for the Israel lobby, bundling and directing funding from a broader group of donors to strategically selected candidates. They do have a Political Action Committee of their own that engages in direct donation but at an order of magnitude less than their “bundling” operations.Not really. There are other Israeli connected pacs that donate to individuals. Sure. There are AIPAC donors that donate to individuals and/or PACs that distribute money to individuals. AIPAC itself has made it policy not to donate to individual candidates. Not really what they do.
That said, if you removed every sitting legislator at the federal level who has taken money from any of those sources, you’d be left with like 8 legislators - Tlaib, Omar, AOC, Hirono, a couple from Cali and the guy from Texas.
You’re correct that the majority of both parties in both chambers accept substantial funding from these groups and you won’t catch me carrying water for any of them on that fact.
