Maher: GOP birthers think Obama's race is "un-American"

Bill Maher, upon learning that 51 percent of Republican voters now believe that President Barack Obama was not born in the United States, thus making the GOP majority birthers, he asked his conservative panel, "At what point do you say, I can't be a Republican anymore?"

Maher attributed the birthers' views to Obama's race.

"There is nothing about this man that is un-American, except, to them, his color,"

The segment was originally broadcast on HBO on "Real Time with Bill Maher," on March 25, 2011. Watch the clip at Mediaite (not embeddable.)
