Christian Vs. Muslim

I don't believe our president is Muslim, but I'm not sure he is Christian, either. Has he made a public profession of faith, like what it says in Romans 10: 8-10? You can tell by his deeds according to James 2:14-26. Just because someone is born in a certain place, like America, doesn't mean he is a Christian. It's what comes out of the mouth that shows what is inside.
