It's fascinating that nobody here thinks a politician's faith should matter. It's nice in a way, although as a more-or-less atheist myself I kind of care if my politicians choose to believe in fairy tales, I feel it perhaps doesn't reflect well on them (I don't mean that to sound TOO harsh, I was once a born-again Christian myself).
In the UK, Clegg's admitted lack of faith probably will hardly matter a jot. I find it quite sad that a survey here in the States showed that a large number of Americans would be put off of voting for a candidate who admitted to being an atheist (more than would be put off by someone who was a believer in a different faith to their own).
