The Zionist lobbies

"The divide between American pro-Israeli activists and other U.S. Jews is not particularly new. Many pro-Israel groups, as well as the Israeli government, supported the 2003 invasion of Iraq. But American Jews as a whole opposed the war by a 3-1 margin, Gallup found in 2007 — making them more strongly anti-war than any other U.S. religious group." (thanks Dina)
