Alaska Gov. Sarah Palin will be stumping with Georgia Sen. Saxby Chambliss on the eve of his Dec. 2 runoff.
Palin, who was a hit with the conservative GOP base as she ran for vice-president, will join Chambliss at four rallies across Georgia.
Chambliss is running off against Democrat Jim Martin in a race that could help determine whether Democrats have enough votes to block GOP filibusters in the U.S. Senate.
Responding to the Palin announcement, Chambliss said, "We've got the wind at our backs."
Georgia is one of two unresolved contests. The other is in Minnesota, where a recount is under way in the race between Republican Sen. Norm Coleman and Democrat Al Franken.
