BILL MAHER: Now I know they hate it when I say it, but the word for Republicans these days is promiscuous. First they fell in love with Trump because they remembered him from back in the '80s when they were young and happy and their penises worked. But the Donald turned out be a lot like his hair: ridiculous, difficult to control, and not very believable.
So then they switched to Michele Bachmann, but she lacked a certain gravitas, or whatever the Latin word is for brain. And she had some skeletons in her closet like her husband.
So then they dropped her and convinced Rick Perry to run. Oh, yes, finally the conservative they were all looking for, but then something horrible happened: Rick started talking, and he sounded so dumb that now they're even considering voting for a black guy.
Maher has taken two other racial swipes at Cain. In May, the liberal host said "Republicans say they love him so they're not racist - right." He followed that up the next month by saying about Newt Gingrich, Let me put your unpopularity in context for you - you're a Republican and you're polling behind a black guy."
In addition to these rants, Maher has sued the "twat" and "cunt" slurs against Sarah Palin.
The liberal blog Alternet earlier this year attacked Cain as a "sellout," a "monkey in the window" and "apologist for white racism."
And they call Tea Party members and conservatives "racists" and "women haters?"
