From the Chron:
23 percent of Texans are convinced that Democratic presidential nominee Barack Obama is a Muslim.
Obama is a Christian who was embroiled in a controversy earlier this year about his two-decade membership in Chicago's Trinity United Church of Christ. Yet just 45 percent of those polled identified the Illinois senator as a Protestant.
The Obama-is-a-Muslim confusion is caused by fallacious Internet rumors and radio talk-show gossip. McCain went so far at one of his town hall meetings to grab a microphone from a woman who claimed that Obama was an Arab.
The Texas numbers are unusual because most national polls show that just 5 to 10 percent of Americans still believe Obama is a Muslim — less than half the number of Texans who buy into the debunked theories.
