His answers about religion sound like he wants to have all his bases covered and is not willing to admit to a specific belief. I do not trust him at ALL.
I agree with you - I think he is an extremely devious and dangerous person. He's an empty suit, in real terms, but at the same time, like many empty suits, he has demagogue capabilities and he certainly has a personally devoted following out there on the left.
I'll go you one better. I suspect he is basically an opportunist, but you will see that opportunism turn to overt Islam once he gets elected. Watch for a high-profile "conversion" to Islam once he's president.
