At his rally Wednesday in Atlanta, Romney made only a passing reference to Gingrich, noting that Gingrich and Santorum had "spent a lot of time in Washington." At the mention of Gingrich's name the crowd of several hundred booed loudly.
Outside, six people stood with small homemade signs supporting the former congressman.
Rep. Phil Gingrey, another Gingrich backer from Georgia, acknowledged that Georgia would be a fight with Santorum and Paul still in the race, peeling off conservative voters.
"I do believe Newt will win Georgia," he said, "but it will be closer than it otherwise might have been."
