Can Herman Cain Last?

More polls are boding well for Herman Cain: CBS News has him tied with Mitt Romney at 17 percent, while Public Policy Polling shows him leading in North Carolina, Nebraska, and West Virginia. So can Cain actually win? Probably not, says Tom Jensen at PPP. “The thing fueling Cain's lead in all of these states is strong support from the furthest right segment of the Republican electorate,” Jensen writes. “This most conservative group of Republican voters has been shopping for a candidate all year. They've gone from Huckabee to Trump back to Huckabee to Bachmann to Perry and now to Cain. I would expect their support for Cain to be pretty temporary. One thing that's been very clear through all these twists and turns though—they're not going to support Romney.”
