Another one bites the bus

Obamamania throws another supporter under the bus.

This time it's Bernie Mac....

Toward the end of a 10-minute standup routine at the Hyatt Regency Hotel in downtown Chicago, the 50-year-old star of "The Bernie Mac Show" joked about menopause, sexual infidelity and promiscuity, and used occasional crude language.

"My little nephew came to me and he said, 'Uncle, what's the difference between a hypothetical question and a realistic question?'" Mac said. "I said, I don't know, but I said, 'Go upstairs and ask your mother if she'd make love to the mailman for $50,000.'"

As the joke continued, the punchline evoked an angry response from at least one person in the audience, who said it was offensive to women.

"It's not funny. Let's get Barack on," a man shouted from the crowd, which paid $2,300 each to support the Illinois senator.
