A new Pew poll finds that the number of Americans who say Pres. Obama is a Christian dropped from 48 percent in March of 2009 to 34 percent now. The portion who say he is a Muslim grew from 11 percent to 18 percent.

The poll was completed before Obama’s recent statement supporting the right of Muslims to build a mosque near Ground Zero in New York.

There was a strong correlation between those who approve of Obama and those who say he is a Christian, and vice versa for those who disapprove and say he is a Muslim. Full poll summary here.
