"Gingrich and Paul may have convinced themselves that they are trying to save the country, while being less inclined to recognize or acknowledge that they're enjoying the attention and perks. They both do seem to be having a good time."
It was his second big defeat in the South in two weeks, underlining the futility of his White House bid. Gingrich represented Georgia in Congress for two decades and built his campaign around expected strong showings in the conservative region.
Rick Santorum, with seven state wins in March alone, has taken the mantle of the conservative alternative to front-runner Mitt Romney, the former governor of Massachusetts. With even Santorum under pressure to end his campaign to further party unity, Gingrich's White House bid looks even more quixotic.
Yet Gingrich - who won only 16 percent support in Louisiana, one of the states he was supposed to do well in - has vowed to stay in the race until the Republican convention in Tampa, Florida, in August.
