I don't think Obama is stupid at all - I DO however think that his entire life is scripted and rehearsed, and that everything he says is carefully planned, polled and tested beforehand.
Because he wants to be the messiah you so badly need him to be.
When he goes off-script, it shows he is a human, and therefore imperfect.
You meatheads can't handle that, and I suspect he can't either. Messiah complexes are not just for religious cult leaders.
