NORCROSS — U.S. Sen. Raphael Warnock made his final campaign stop Tuesday, urging voters to “get in line and please stay in line” to help him get over the finish line in his runoff against Republican Herschel Walker.

“The truth is my opponent still could win this election,” Warnock said. There is a path.”

Warnock said he was heartened by early voting turnout, which tends to favor Democrats. But Republicans are more likely to show up on election day to cast ballots, and that could chip away at his advantage.

“The job is not done,” he said.

The media appeared to outnumber supporters at Warnock’s stop in a Gwinnett County office park. A bank of about 20 television cameras were on hand as he took questions from reporters. A light rain fell as Warnock spoke.

“I’ve seen people standing in the rain for concerts and you know a whole range of things,” he said of the role weather could play in limiting turnout. “There’s really too much at stake to take this election lightly.”

Amid reports of long lines at some metro Atlanta polling places, Warnock said if he is reelected he would push for changes to make voting easier.

“Look, I had to sue the state of Georgia to get Saturday voting, and clearly we needed it,” he said. “That only relieves some of the pressure.

“I do have some ideas on the other side of this about the work we must do because we ought to be making it easier, not harder, for people to vote.”

Warnock has often said during the campaign that it was a contest of “character and competence,” which brought attention to allegations against Walker of abuse of his ex-wife and other women, falsehoods about his academic record and law enforcement experience, and exaggerations about his business background.

Walker, however, said at his own election day campaign stop earlier in the day that he would “put my character up against Raphael Warnock any day.

“My opponent says many things,” Warnock replied. “You can’t believe any of them.”
