Republican Sen. Johnny Isakson has agreed to only one debate against his two opponents in the Georgia Senate race.

The two-term Republican will debate Democratic nominee Jim Barksdale and Libertarian Allen Buckey on Oct. 23, six days after early voting begins in Georgia, The Atlanta Journal-Constitution reported.

“If my Democrat opponent would like to offer any substantive policy positions that he stands for, I encourage him to follow suit and openly and transparently answer questions from Georgia media as I have always done and will continue to do,” Isakson said in a statement.

The sole debate will be held at the Atlanta Press Club. Barksdale had wanted a series of debates in all of the state’s media markets. His campaign manager Dave Hoffman said it was “clear” Isakson “is not working for the people of Georgia and he doesn’t want to talk about it.”

A recent Journal-Constitution poll showed Isakson up by 6 points over Barksdale, 44 percent to 38 percent, in the Senate race. With Donald Trump at the top of the ticket and changing demographics in the Peach State, Democrats have grown increasingly optimistic about their chances in Georgia, which has not voted Democratic for president since 1992 and has not elected a Democratic senator since 2000.
