i wonder if this isn't more of an indication of the extent to which the president is disliked by people who identify themselves as republicans, rather than an indication of a change in belief about the president's relgiion. no new facts have come to light that may convince someone that obama is a muslim since october 2008. among a certain portion of the american public, many (although by no means all) of whom are republicans, "muslim" has a strongly negative connotation. to an anti-muslim bigot, telling a pollster that the president is a "muslim" is a way to slap a negative label on him. i wonder if this isn't anything more than that.
