Whether or not your arguement holds water that "around here" people think being Muslim is criminal...let's look at an important fact.
If Obama was a Muslim, and has become a Christian- regardless of his sincerity- he's now a target for islamic extremists.
As to other reasons he's qualified or not qualified for being POTUS, the position he's in as an apparent former Muslim- disqualifies him.
Obama will not be defeated by a single bullet (former Muslim, goofy church, no experience) he's one to be destroyed by a thousand patient cuts.
That's true in general. Presidents are supported on their totality and candidates are opposed on their totality. There are certain themes that work to one extent or another, but they have to be broad: Bush is dumb, Kerry is elitist.
The theme should be that Obama is a neophyte and empty suit and we tailor each attack to that theme. The Muslim stuff just comes off as mean and bigoted, even though it isn't. Let the Hillary camp do that whisper campaign.
And as the leader of the Great Satan President Bush isn't???
As to other reasons he's qualified or not qualified for being POTUS, the position he's in as an apparent former Muslim- disqualifies him.
Last time I checked Article VI, Section 3 was still a part of the Constitution.
