This is interesting, I thought:

A new poll finds that the more often Americans go to church, the more supportive they are of U.S. foreign policy, including the war in Iraq.

The poll by Public Agenda finds that people who frequently attend worship services are far more likely to support the war on terror and believe that the United States is achieving its objectives in Iraq.

Americans who never attend worship services are much more likely to believe that the war is damaging international relations and is costing too much in money and casualties.

Public Agenda’s Michael Remaley said the poll reflects evangelical Christians’ greater tendency to view the world in terms of good and evil, and their support for President George W. Bush.

I think Public Agenda’s Michael Remaley is right, but I think he ignores something about people of faith.  They don’t question things as much as non-believers (generally speaking).  An authority figure gets up there and tells them that X and Y are sins, and they all nod their head in agreement (he’s at the pulpit, he must know what he is talking about).  The same applies to President.  There’s a certain "sheep factor" here, which can’t be overlooked.
