Democratic gubernatorial candidate Stacey Abrams’ campaign said Wednesday that with less than 16,000 ballots needed to force a runoff with her Republican opponent, Secretary of State Brian Kemp, her path to collect every outstanding vote could include litigation.

Abrams campaign manager Lauren Groh-Wargo joined with Dara Lindenbaum, senior counsel at Washington’s Sander Reiff Lamb Rosenstein & Birkenstock, to announce that the campaign estimated that at least 15,000 paper absentee ballots remained uncounted. They said those ballots were cast primarily in Gwinnett and Clarke counties, which is home of the University of Georgia.
