Barak Obama

As Americans are preparing to select their presidential candidate, it looks like Barak Obama is leading the polls as against Hillary Clinton. Has any one thought of his religeous beleifs? Does anyone knows what he believes in.
Supposing he was a Muslim, are Americans ready for a Muslim president? I know some people will start talking about equal rights but considering the current level of terrorism, do we still have to talk about equal rights? I don't know about his religeous beleifs but Americans will have to be extra careful and investigate him fully before they vote in masses for change.
