Stacey Abrams, the Democratic candidate in Georgia’s gubernatorial race, criticized Republican Governor Brian Kemp for his opposition to legalized sports betting, saying the state is losing potential tax revenue to neighboring Tennessee.

In a move timed to the start of the college football season, the Abrams campaign on Monday released an online ad aimed at sports fans and showcasing the popular University of Georgia Bulldogs football team.

“While Georgians still place bets, Kemp is forcing them out of state to do it, taking the tax dollars with them,” the ad says.

Kemp opposed legalized sports betting in 2018, when he ran against Abrams the first time, but now is taking no position on the subject, spokesman Tate Mitchell said in an email.
