(CNN) - Add Mitt Romney to the list of big name Republicans who are lending a hand to Sen. Saxby Chambliss, as he fights for his political life.
Chambliss is the freshman Republican senator from Georgia who will face off against his Democratic opponent, former state lawmaker Jim Martin, in a runoff election on Tuesday December 2.
Chambliss won a plurality of the vote two weeks ago on Election Day, but Georgia state law calls for the winner to grab 50 percent plus one vote. Do to the inclusion of a third party candidate, Chambliss fell just shy of that threshold, forcing a runoff contest.
Last week Senator John McCain returned to the trail to campaign with Chambliss, just nine days after losing the presidential election to Barack Obama.
Sunday former Arkansas Governor Mike Huckabee, who ran for the Republican presidential nomination before dropping out in March and backing McCain, campaigned with Chambliss.
Romney will join Chambliss on the campaign trail in Atlanta and Savannah this Friday, according to an announcement today from a spokesman. The spokesman also announced that Romney is contributing $5,000, through his Free and Strong American PAC, to Chambliss to help with the runoff election. Romney's PAC donated $2,300 to Chambliss earlier this fall.
Like Huckabee, Romney was a candidate for the GOP presidential nomination before dropping out in February and endorsing McCain. Both Romney and Huckabee could have designs on making another run for the White House.
