Well, about 40% of Americans think Obama is Muslim.
Ever seen his interview with George Stephanopolous? Paraphrasing: Obama said he would not let anyone question his Muslim faith. Then Stephanopolous steps in and says "you mean your Christian Faith?" Obama: "ummm yeah, my Christian faith." Additionally, he did attend Muslim prayers with his stepfather as a kid. There is more that certainly qualifies as "smoke".
I was raised Catholic. You know what you feel on the inside. I don't think he misspoke. "Just Saying".
