Kemp: Abrams' refusal to concede 'a disgrace to democracy'

ATLANTA - Republican Brian Kemp is pressing Democrat Stacey Abrams to concede Georgia's tight gubernatorial race as civil rights groups urge her to stay and fight.

Kemp's campaign issued a statement Saturday saying it's "mathematically impossible" for Abrams to even force a runoff. It calls Abrams' refusals to concede "a disgrace to democracy."

"This is not how America works," Kemp's Communications Director Ryan Mahoney said. "Brian Kemp earned a clear victory on Tuesday night and holds a sizable lead as remaining provisional and military ballots are counted.

Abrams says she will not concede until her camp is certain every vote has been counted.

Just 64,000 votes separate the candidates, putting Kemp at 50.3 percent of the vote.

On Saturday, a rally was held by voters in Smyrna urging Abrams to keep fighting for the vote.

The Southern Christian Leadership Conference is also backing Abrams and encouraging her camp to press on.
