I mean he says he is. There's a lot in his personal biography that emphasizes that that he is a born-again Christian. An awful lot. We know that he used to do cocaine, and was an alcoholic. We also know that his family had business dealings with the Saudis. Can we really trust that this guy is who he says he is and was not a Muslim Manchurian Candidate funded by jihadis to start the war in Iraq and bring on a religious holy war? Just as I would ask of all those people who claim that Obama is a Muslim, prove Bush is not actually a Muslim.
