What goes around comes around on the campaign trail. Just ask businessman David Perdue (R).

Former Georgia secretary of state Karen Handel (R) on Wednesday endorsed Perdue's GOP runoff opponent, Rep. Jack Kingston (R), eight days after the primary election in which she finished third and was eliminated from competition.

That's the same Handel who butted heads with Perdue after he took a dig at her education during the campaign.

"I mean, there’s a high school graduate in this race, okay. I’m sorry, these issues are so much broader, so complex," Perdue said in January.

Handel (surprise!) did not respond to the comment warmly. Neither did Sarah Palin, who backed her.

Handel's Wednesday statement was all about Kingston. She praised his record and his conservative bona fides.

"What I’ve seen in Jack is a man of integrity who is devoted to his family. A man who is fiercely dedicated to the conservative principles that are the foundation of the Republican Party. A man who has represented the people of the 1st Congressional District honorably and effectively for more than 20 years," Handel said.

But we'll let you decide whether Perdue's comment had anything to do with it.
