Republican Karen Handel on Tuesday released her first TV ad of the runoff cycle, a 30-second introductory spot that highlights her 25 years living in Georgia's 6th District.

"We just love this community. It's home for us," the former Georgia secretary of state said in the ad. "To be able to do good for the people of this district who aren't just constituents to me, they are friends to Steve and I. It would be extraordinary and a real privilege."

The ad was an implicit dig at Democrat Jon Ossoff, her opponent in the June 20 runoff, who has faced an onslaught from critics because he doesn't live in the suburban Atlanta district. He lives a few miles south of the district near Emory University, where his fiancee attends medical school, and said he intends to move.

It was Handel's first ad since she finished in second-place in the April 18 special election to land a spot in the runoff against Ossoff, a 30-year-old former congressional aide. National Republican groups have poured in millions to fill the void, worried that an Ossoff upset could be an embarrassing disaster for the GOP.

The race is already on track to cost more than $30 million, making it the costliest U.S. House contest in the nation's history. Ossoff has laid out more than $6.6 million in advertising between April 18 and June 20, and on Tuesday he launched an attack ad targeting Handel's "unforgivable" tenure with a breast-cancer charity.
