Here is some help.
Of course, you probably don't even know who AIPAC is.
The American Israel Public Affairs Committee (AIPAC) has weighed into the debate big time, unleashing hundreds of its activists on Capitol Hill, buttonholing congressmen and staffers alike. This is how it works according to a congressional staffer: "First come the phone calls from constituents who are AIPAC members. They know the Congressman and are nice and friendly and just tell him, or whichever staffer the constituent knows, just how important this vote is to him and his friends back in the district. Then the donors call. The folks who have hosted fundraisers. They are usually not only from the district but from New York or LA or Chicago. They repeat the message: this vote is very important. Contrary to what you might expect, they do not mention campaign money. They don’t have to. Because these callers are people who only know the Congressman through their checks, the threat not to write any more of them is implicit. Like the constituents, the donors are using AIPAC talking points which are simple and forceful. You can argue with them but they keep going back to the script… Then there are the AIPAC lobbyists, the professional staffers. They come in, with or without appointments. If the Congressman is in, they expect to see him immediately. If not, they will see a staffer. If they don’t like what they hear, they will keep coming back. They are very aggressive, no other lobby comes close. They expect to see the Member, not mere staff. Then there are the emails driven by the AIPAC website…and then the ‘Dear Colleague’ letters from Jewish House members saying how important the vote is for Israel and America. They also will buttonhole the Members on the House floor… And, truth be told, all the senior Jewish Members of the House are tight with AIPAC. Also, the two biggest AIPAC enforcers, House Majority Leader Eric Cantor and his Democratic counterpart, Democratic Whip Steny Hoyer, are fierce AIPAC partisans, and they make sure to seek out Members on the floor to tell them how they must vote. On anything related to Israel, they speak in one voice: AIPAC’s. Obviously, there is no counterpart to this on the antiwar side. No anti-AIPAC to speak of. AIPAC owns this issue. It gets what it wants."
