Is that even legal under US law? Apparently it is in some states. Federal law does not, apparently, prohibit political discrimination. But some states do - California, New York, DC, Colorado, and North Dakota.[1]
This should be reported to the FBI's Foreign Influence Task Force.[2] Anyone involved in such suppression activities may be considered an "unregistered foreign agent".[3] Anyone or any organization attempting to influence US policy on behalf of a foreign government is supposed to register. Here's the database.[4]

Incidentally, the founder of AIPAC, Isaiah Kenen registered twice with the U.S. Department of Justice under the Foreign Agent Registration Act (FARA) as an agent for Israel. Prior to leading AIPAC, he was the leader of the American Zionist Council. He was also chief information officer for the Israeli Ministry of Foreign Affairs.
AIPAC's mission is pretty clear: to promote the interests of Israel. This is fine, and not unique, but that seems to me to be the textbook definition of a foreign agent, and it should be registered as such.
AIPAC has a very large budget and will be spending over $100M in 2024 to defeat any candidate for US Congress that did not align with their pro-Israel goals.
