ATLANTA, Ga – Saturday voting is being held today in the nation’s most closely watched congressional election and the first in Donald Trump’s presidency.

Early voting has been underway since March 27 in the 6th congressional district, a contest in which 18 candidates are vying to replace Tom Price, now President Donald Trump’s secretary of the U.S. Department of Health and Human Services.

April 8 is the only opportunity for Saturday voting. Early voting runs through April 14, and the actual election is being held on April 18. The only way to avoid a June 20 runoff would be if one candidate receives 50 percent-plus-one, almost an impossibility in such a crowded race.

An exclusive poll commissioned by 11Alive News and conducted by SurveyUSA shows Democrat and political newcomer Jon Ossoff dominating the race with 43% of the vote, followed by Republicans Karen Handel (15%), Bob Gray (14%), and Dan Moody (7%).
