No, he reversed that and he said he would have no problem with putting a Muslim in his cabinet and also appointing one to be a Federal Judge.
With that one, he just disqualified himself from being President.
Well,crap...
A little information can be a misleading thing:
FTR, he did not reverse himself: he said he would absolutely not appoint anyone believing in Sharia Law — which is what he always meant and in effect the same thing. Frankly, I think the odds of him appointing any Muslim is less than zero.
