He’s never going to shake her off.

Not all by himself.

The very fact that he can’t shake her off has become her best argument against him. “Why can’t he close the deal?” Hillary taunted at a polling place on Tuesday.

She’s been running ads about it, suggesting he doesn’t have “what it takes” to run the country. Her message is unapologetically emasculating: If he does not have the gumption to put me in my place, when superdelegates are deserting me, money is drying up, he’s outspending me 2-to-1 on TV ads, my husband’s going crackers and party leaders are sick of me, how can he be trusted to totally obliterate Iran and stop Osama?

Now that Hillary has won Pennsylvania, it will take a village to help Obama escape from the suffocating embrace of his rival. Certainly Howard Dean will be of no use steering her to the exit. It’s like Micronesia telling Russia to denuke.

“You know, some people counted me out and said to drop out,” said a glowing Hillary at her Philadelphia victory party, with Bill and Chelsea by her side. “Well, the American people don’t quit. And they deserve a president who doesn’t quit, either.”
