UPDATE: Around 10PM ET, McCain rejected the endorsement of another right-wing pastor, Rod Parsley, "an Ohio preacher who has sharply criticized Islam and called the religion inherently violent."
[I]n an interview with The Associated Press, McCain said he rejected Parsley's support, too.
"I believe there is no place for that kind of dialogue in America, and I believe that even though he endorsed me, and I didn't endorse him, the fact is that I repudiate such talk, and I reject his endorsement," McCain told the AP. ...
[Parsley] has described Islam as an "anti-Christ religion" and the Muslim prophet Muhammad as "the mouthpiece of a conspiracy of spiritual evil," according to ABC News.
