Another one bites the dust
ADDENDUM: I addressed this in the comments, but it should be said here.
It's one thing to exclude someone from the presidency because he rejects the separation of church and state, or because he believes something else that Islam teaches. But to reject him because he's a Muslim is another matter.
The Constitution says that there should be "no religious test" for public office. It's kind of hard for me to see how anybody could reject that very clear dictum from the Constitution and still claim to be, in any sense, a constitutionalist.
