Watch out, Mitt. A new Rasmussen poll has Newt Gingrich surging to a sizable lead over Mitt Romney, 38 percent to 17 percent. Support seems to be draining from Rick Perry and Herman Cain, who come in with 4 percent and 8 percent, respectively. In a matchup with President Obama, Gingrich has a slight lead, 45 percent to 43 percent. In that scenario, the Rasmussen poll is a bit of an outlier, with a Real Clear Politics composite of seven major polls showing Gingrich trailing Obama by nearly 6 points. Meanwhile, Gingrich isn't modest: He told ABC News that he would be the GOP nominee.
