Speaking to an audience of 2,000 people in an Atlanta suburb, the former Massachusetts governor obliquely criticized his rival's pledge to bring gas prices down to $2.50 a gallon.
"I’m not gonna come here and pander to you and say here’s what your gasoline price will be if I do all those things," Romney told the audience.
Both his and Gingrich's energy plans propose easing regulations on energy production, expanding domestic drilling and approving the Keystone oil pipeline from Canada.
Gingrich has pointed to his gas-price pledge as an issue that differentiates himself from his opponents.
The former House speaker is focusing much of his energy in the state he represented in Congress, staking his presidential hopes on a win there to inject energy into his flagging campaign.
A Romney senior strategist said the former governor's campaign did not expect to win both Tennessee and Georgia, but said Romney was looking to pick up delegates awarded proportionally in certain districts in those states.
"More important than winning this state or that state is achieving the requisite number of delegates you need to obtain the nomination," said Eric Fehrnstrom. "That's what our focus is on."
