Another sign of Cain peaking out

The online betting operation Intrade had his chances of winning the Republican nomination at 11 percent two weeks ago. Still a long-shot, but at least within some range of possibility. Now, he's at 5.4 percent - and the reports of accusations that he sexually harassed women won't help matters. (He denies any impropriety.) This would ordinarily set the stage for a Rick Perry comeback, but the Texas governor is such a goofy, unappealing campaigner that his ascension isn't a sure thing. By the way, Mitt Romney now has a 70 percent chance of winning the nomination, according to Intrade.
