Here’s an interesting survey, Jews show the least support for the war in Iraq than any other religious group. Mormons show the most support:

Of these major religious groups, three show more opposition than support for the war:

• Jewish people oppose the Iraq war by a better than 3-to-1 margin, 77% to 21%.
• Americans without a religious preference are twice as likely to oppose (66%) as to support (33%) the war.
• Catholics are somewhat more likely to oppose (53%) than to support the war (46%).

On the other hand, Mormons and Protestants show more support than opposition to the war. Mormons are strongly in favor, as just 27% term the war “a mistake.” Overall, Protestants are divided, with 48% opposed and 49% in favor. But black Protestants and non-black Protestants diverge in their views. Black Protestants — who are overwhelmingly Democratic — show strong opposition to the war, while among non-black Protestants, support for the Iraq war surpasses the majority level (55% say the war was not a mistake).

The widespread Jewish opposition to the war in Iraq is not a recent development as the majority of all Americans have come to oppose the war in the past two years. Even in 2003 and 2004, when more Americans favored (52%) than opposed the war (46%), 6 in 10 Jews (61%) were opposed to it.

And during the run-up to the war in late 2002 and early 2003, U.S. Jews were divided in their views on whether to invade Iraq to remove Saddam Hussein from power (49% were in favor, 48% opposed). At that time, Americans overall favored an invasion by a 57% to 37% margin.
