. . .The Pew poll found that about three in 10 of Obama’s fiercest political rivals, Republicans and conservatives, say he is a Muslim. That is up significantly from last year and far higher than the share of Democrats and liberals who say so. But even among his supporters, the number saying he is a Christian has fallen since 2009, with just 43 percent of blacks and 46 percent of Democrats saying he is Christian.

Among independents, 18 percent say Obama is Muslim – up from 10 percent last year.

Pew analysts attribute the findings to attacks by his opponents and Obama’s limited attendance at religious services, particularly in contrast with Presidents George W. Bush and Bill Clinton, whose worship was more public.
