The other Republicans in the contest are facing mounting pressure to go on the offensive. Club for Growth, a conservative super PAC that endorsed Gray, suggested in a memo it could soon target Handel. And other campaigns are increasingly throwing elbows at Gray, including questioning his pro-Trump credentials.
The district, which stretches from east Cobb to north DeKalb, has long been a Republican stronghold. But Donald Trump's struggles in the area, along with Ossoff's surprising rise, have given Democrats hope they can flip the seat vacated by Tom Price.
The poll shows Ossoff would be virtually deadlocked in a head-to-head matchup with the four top Republicans in the poll. The scenarios showed Ossoff with narrow leads over Gray, Moody and Handel in hypothetical matchups, while Hill has a one-point lead over Ossoff in the contest.
The poll surveyed 462 registered voters in the 6th District, and has a margin of error of 4.5 percent.
