Herman Cain’s star is continuing to rise, according to a new Public Policy Polling poll released Wednesday that shows him tied for second place with Sarah Palin in the first-in-the-nation caucus state of Iowa.

Cain is taking the nation by storm in terms of his polling results: following the first Republican Primary debate in Greenville, South Carolina, a focus group conducted by Frank Luntz declared him the unanimous winner. He led in the most recent Daily Caller/Conservative Home Tracking Poll, and continues to lead the pack in positive intensity score in Gallup’s polling. A CNN poll released May 27 had the supposed dark horse candidate among the top five, ahead of Newt Gingrich, Michele Bachmann, and Tim Pawlenty.

With Huckabee and Trump, who took first and third respectively in the last polling PPP did in Iowa, out of the race, Romney leads the pack of primary contenders in Iowa, despite the fact that he has made little play to compete in the state.
