An excerpt from the article: 

The race could be complicated by the still-undecided fate of ObamaCare. Trump has been determined to repeal and replace it, but the House GOP’s first attempt proved deeply unpopular nationally. With Price playing a significant role in those negotiations, the issue could have an outsized impact in his old district.

For both sides, the race looks set to hinge on voter enthusiasm. Republicans are still favored now that the party has one candidate, but Democrats are emboldened by their near-majority margin last Tuesday, hoping that a few more weeks of campaigning will push Ossoff into a historic upset.

“It’s not clear that the 6th District is a safe Republican district now. It may be,” Barke said. “Maybe the Ossoff turnout in April could have been a fluke. But that’s going to be up to the Democrats.”
