If you haven't seen it, here it is:
Yesterday, on Fox News he tried to clarify his view by saying:
This is America and we have a constitution. And we do not put people at the leadership of our country whose faith might interfere with them carrying out the duties of the constitution. So if, for instance, you believe in a theocracy -- I don't care if you're a Christian -- if you're a Christian and you're running for president and you want to make us into a theocracy, I'm not going to support you. I'm not going to advocate you being the president.
I don't care what religion or faith someone belongs to, if they're willing to subjugate that to the American way and to our constitution, then I have no problem with that.
And I agree with Dr. Carson on that. We should not elect Christians or Muslims unless they renounce all biblical and sharia laws -- at least those that are contrary to our constitution (which is nearly all of them).
