At a McCain rally in Davenport, IA, yesterday, while delivering the invocation, Arnold Conrad, a minister, said:

There are millions of people around this world praying to their god -- whether it's Hindu, Buddha, Allah -- that [Obama] wins, for a variety of reasons. And Lord, I pray that you will guard your own reputation, because they're going to think that their God is bigger than you, if that happens. So I pray that you will step forward and honor your own name with all that happens between now and election day.

Which is the kind of thing that McCain, already trying to clamp down criticism of Obama at his rallies, doesn't need. The campaign released this statement, distancing itself from Conrad's comments:

While we understand the important role that faith plays in informing the votes of Iowans, questions about the religious background of the candidates only serve to distract from the real questions in this race about Barack Obama's judgment, policies and readiness to lead as commander in chief.
