Republican Karen Handel and Democrat Jon Ossoff crisscrossed Atlanta's suburbs over the weekend to appeal to their likeliest voters in the final days ahead of Tuesday's 6th District vote, as polls showed a neck-and-neck race and few voters still undecided.

Handel rallied the GOP faithful at an event featuring two Cabinet secretaries with deep ties to the district — former Rep. Tom Price and ex-Gov. Sonny Perdue. Ossoff countered with his own big-name supporter, Rep. John Lewis, with stops in some of the bluest parts of the suburban territory.

It's the most closely-watched election in the nation, attracting droves of attention and heaps of cash. By far the most expensive U.S. House contest in history, both sides eager to win it for very different reasons.

Handel’s closing pitch meant emphasizing her roots in the 6th District, which spans from east Cobb to north DeKalb, and reminders that Ossoff doesn’t live in the territory he hopes to represent. The Democrat lives south of its borders, near where his fiance is attending medical school at Emory University, and plans to move within its boundaries.

“I know this district and the people of this district know my record,” she said at one campaign stop. “They know what I’ve been able to accomplish. That’s why I’m going to win.”

Ossoff's weekend took him to stops on the outskirts of downtown Marietta, Sandy Springs and Dunwoody — all areas where he performed well in the April 18 vote. He narrowly missed an outright win in that first round of voting, cutting a swath of support across north DeKalb and up the Ga. 400 and I-75 corridors.

"It's all about turnout and it's all about getting out the vote," he told supporters in Chamblee. "And my team and I are working as hard as we ever have to make sure they know when and where to vote. We're going to sprint through the finish."
