Americans increasingly are convinced - incorrectly - that President Barack Obama is a Muslim, and a growing number are thoroughly confused about his religion.
Nearly one in five people, or 18 percent, said they think Obama is Muslim, up from the 11 percent who said so in March 2009, according to a poll released Thursday. The proportion who correctly say he is a Christian is down to just 34 percent.
The largest share of people, 43 percent, said they don't know his religion, an increase from the 34 percent who said that in early 2009.
The survey, conducted by the nonpartisan Pew Research Center and its affiliated Pew Forum on Religion & Public Life, is based on interviews conducted before the controversy over whether Muslims should be permitted to construct a mosque near the World Trade Center site. Obama has said he believes Muslims have the right to build an Islamic center there, though he's also said he won't take a position on whether they should actually build it.
In a separate poll by Time magazine/ABT SRBI conducted Monday and Tuesday - after Obama's comments about the mosque - 24 percent said they think he is Muslim, 47 percent said they think he is Christian and 24 percent didn't know or didn't respond.
