(CNN) – Nine days after losing the presidential election to Barack Obama, John McCain is back on the campaign trail.
The former GOP presidential nominee will stump for fellow Republican senator Saxby Chambliss today in Georgia.
The freshman senator most likely faces a run-off election December 2 against Democrat Jim Martin, a former state lawmaker.
At the start of the campaign, Chambliss was the heavy favorite in the race. But the contest tightened, and neither candidate won more than 50 percent of the vote on Election Day, thanks in part to a third-party candidate who won 3 percent of the vote. The race appears headed to a runoff between Chambliss and Martin.
The runoff is expected to become official later this week, after the state certifies the election results. Unofficial tallies show Chambliss with 49.8 percent of the vote, just short of the 50 percent plus one vote need to win. Martin has 46.8 percent of the vote.
