Smart piece from National Journal: “Newt Gingrich has all the marks of a dead candidate walking: He hasn’t won a contest since South Carolina nearly six weeks ago and he never seriously competed in either Michigan or Arizona, where he finished at the back of the pack. But instead of winding down, Gingrich’s campaign—or at least the one being waged on his behalf—is set for its most aggressive push yet. According to a source close to Winning Our Future, the super PAC supporting Gingrich, the group begins an ad blitz on Wednesday in seven upcoming primary states, including  many holding contests next week on Super Tuesday. The ads are thanks to yet another contribution from Las Vegas casino magnate Sheldon Adelson, who, along with his wife, has already contributed $10 million to the PAC.”
