Palin's presidential chances in freefall

Intrade, the online trading site, gives her an 11 percent chance of becoming the presidential nominee, down from 20 percent a couple of days ago. It's still early and all that, but she's clearly being done in by the weekend shooting - not so much from her loyal fan base (they won't abandon her, no matter what), but from the GOP establishment that, fairly or not, is likely to view her as damaged goods.
