Nevermind. It will probably show up on this thread. Have a great day...
I think it's clear that he merely left out a word such as "putative" or "ostensible" before "Muslim."
From a partisan standpoint, I have to admit that I would have preferred that he had done something that reprised his recital of the shahada (which he recited for the New York Times last year), but I find it clear that this slip was innocuous.
Reciting the shahada was anything but innocuous; it was clear declaration that he is indeed a professing Muslim. It was the most remarkable thing that I remember in any presidential campaign.
This minor verbal slip, though, I believe is not significant.
