Remember during a McCain meeting :
A woman in the public : I've heard Obama is a Muslim, that scares me a lot.
McCain : No, he's not a Muslim. He is a good person.
That's not the exact words, since it's a traduction of what I remember having heard in french, but the sense was that.
I've just found it on youtube. The woman said he's "an Arab" and McCain took the mic off her and said "he's a decent, family man, citizen that I just have to have disagreements with on fundamental issues." Although, you've gotta give McCain kudos for trying to quash all the Muslim/Arab/Kenya rumours.
