As long as they can keep their faith ouf of their policy, I see no problem with it. Who cares if someone is Christian, Muslim, Jew or atheist?
I was very surprised to find that nearly one in five Britons don't want Michael Howard, the leader of the opposition Conservative party, to be Prime Minister just because he's Jewish. For a start, he and his party are so off the radar at the moment I didn't even know he was Jewish, but it's the breadth of the anti-Semitism that really astounded me. It's not even as if he'd be the first Jewish PM, and the previous one, who with the name "Benjamin D'israeli" was hardly covert about his Jewishness, was a pretty successful and well-regarded leader...
