AIPAC is prideful about its influence. Its promotional literature points out that a reception during its annual policy conference, in Washington, “will be attended by more members of Congress than almost any other event, except for a joint session of Congress or a State of the Union address.” A former AIPAC executive, Steven Rosen, was fond of telling people that he could take out a napkin at any Senate hangout and get signatures of support for one issue or another from scores of senators. AIPAC has more than a hundred thousand members, a network of seventeen regional offices, and a vast pool of donors. The lobby does not raise funds directly. Its members do, and the amount of money they channel to political candidates is difficult to track. But everybody in Congress recognizes its influence in elections, and the effect is evident. In 2011, when the Palestinians announced that they would petition the U.N. for statehood, AIPAC helped persuade four hundred and forty-six members of Congress to co-sponsor resolutions opposing the idea.
