Look out, Newt Gingrich: the dark horse is about to overtake you in Iowa. Ron Paul has evaporated Gingrich’s lead from 9 percent to just 1 percent in a new Public Policy Polling survey. Gingrich came out with 22 percent in the poll to Paul’s 21 percent and Mitt Romney’s 16 percent. That wasn’t the only bad news for Newt: his favorability rating with Tea Party voters plunged from 35 percent down to 24 percent. Paul’s overall favorability soared to 61 percent. According to a new Wall Street Journal/NBC News poll, Romney has fallen well behind Gingrich, who has 40 percent of GOP votes compared to Romney's 23 percent.
