Newt Gingrich starts a two-day swing through the Atlanta area Friday, as his chief opponents for the Republican presidential nomination are making it known that they will not cede his old home turf.

Gingrich, a former Georgia Congressman, will hold four public rallies and a fundraiser, bringing along high-profile allies like former presidential contender Herman Cain and members of Georgia’s congressional delegation.

Front-runner Mitt Romney campaigned last week in northeast Atlanta, and fast-rising former Pennsylvania Sen. Rick Santorum is scheduled to appear in Cumming on Sunday. In addition, a Super PAC backing Romney, the former Massachusetts governor, has bought television ad time to attack Gingrich and Santorum’s campaign plans to advertise in Georgia as well.
