Having come back from the political dead at least twice this presidential cycle, Newt Gingrich and his backers vowed to stay in the presidential race Wednesday despite a growing chorus of conservatives calling for him to quit after failing to win either of Tuesday’s two Southern primaries.

Gingrich finished second to former senator Rick Santorum in both Alabama and Mississippi but showed no intention of stepping aside.

Both Santorum and former Massachusetts governor Mitt Romney, who came in third in both of Tuesday’s contests, have declined to call on Gingrich to depart the race, but other Republicans were not shy.
