"GOP voters in Georgia have many choices if they want something said, but Karen Handel is the only choice if we want something done. Karen will get the job done."
Handel is facing a trio of congressmen and a big-spending businessman in her primary, and has struggled with fundraising this election cycle.
Palin endorsed Handel in her run for governor four years ago as well, helping her make the primary runoff against now-Gov. Nathan Deal (R).
Palin has been jumping back into the political fray more in recent days. She also endorsed women running in Iowa's Senate race and for an open House seat in Florida this week.
