GOP presidential hopeful Rep. Michelle Bachmann, R-Minn., is now nearly leading in Iowa, according to a new Des Moines Register poll. Bachmann had 22 percent support, just behind former Massachusetts Gov. Mitt Romney's 23 percent backing. Despite the surge, Bachmann is still dogged by her reputation for making erroneous and sometimes bizarre claims. Even Fox News host Chris Wallace raised the issue with Bachmann: "The rap on you in Washington is that you have a history of questionable statements, some would say gaffes," Wallace said. "Are you a flake?" Bachmann didn't like the question, saying that it was "insulting to say something like that, because I'm a serious person." Later in the day, Wallace apologized, saying that he "messed up" and that he "didn't mean any disrespect."
