M J Rosenberg: How AIPAC gets Congress to do its bidding.

"Between 1993 and 1995 I worked for a member of the House Appropriations Committee. That is the body that writes the legislation that provides the money after its Subcommittee on Foreign Operations submits its recommendations which are then quickly approved and, after adoption by the full House and Senate, go to the president for his signature.
Here is how it works. AIPAC provides each staffer on the subcommittee with legislative “language” that spells out precisely what it wants for Israel and the amount of dollars it wants for each provision. The language helpfully arrives in electronic form so the staffer does not have to do anything but drop it into a letter that each legislator writes to the chairman of the committee. Each staffer receives the same “wish list” from AIPAC ensuring that each member of the Subcommittee on Foreign Operations will be requesting the same thing."
