A recent survey by Public Policy Polling found that 51 percent of those who plan on voting in the GOP primary believe that Barack Obama wasn't born in the U.S. On 'Real Time With Bill Maher' (Weeknights, 10PM ET on HBO) Maher offered up a theory as to why so many conservatives embrace "birtherism," and then applied that same theory to Speaker of the House John Boehner, with strange results.

"When they go a little deeper into the polling, they find out this is just based on a general sense," Maher explained. "It just feels to them like [Obama's] a foreigner. Well, you know, John Boehner wears bronzer and goes on crying jags. He just feels like a female to me. Maybe liberals should demand to see his penis."
