WESTERVILLE, OH - AUGUST 07: Supporters of Ohio Democratic congressional candidate Danny O'Connor wait for him to speak at an election-night rally on August 7, 2018 in Westerville, Ohio. With 99 percent of the vote in and less than 1 percent of the votes separating the candidates, the race between O'Connor and Republican challenger Troy Balderson was too close to call by the time the rally ended. Balderson held onto the slight lead as the evening ended. (Photo by Scott Olson/Getty Images)
