ANN COULTER FINALLY OVERSTEPS

The poster girl for pitiful, single GOP men -- think Trekkies with rep ties -- is always offensive. That's her schtick. She's not brilliant; she often tosses out blatant falsehoods and then feigns innocence when caught red-handed; she almost always resorts to personal ugliness when she can't win on substance.

Wednesday night, on "Hannity & Colmes," we learned two things:

•Alan Colmes actually does have a set of testicles.

•Ann Coulter, like her idol Joe McCarthy, has no sense of decency.

During a debate about John Roberts and his qualifications for the U.S. Supreme Court, Coulter coughed up a nasty comment that it seemed OK to "kill" a woman at Chappaquidick.

Colmes muttered something about Coulter's low blow about Ted Kennedy. She wouldn't let it go and spit out this morsel:

Did he or did he not kill a woman at Chappaquidick?

Even Sean Hannity, the Rush Limbaugh wannabe, was silenced by Coulter's vehemence. For a long moment, no one said a word, and in that silence you could almost hear the sound of a million people cringing.
