Herschel Walker is stepping into a new arena.

The legendary Georgia running back, who has played in NFL stadiums and has fought professionally in Mixed Martial Arts (MMA), has entered the political ring. Not as a candidate. Walker is featured in a new television spot on endorsing Republican Congressman Jack Kingston of Savannah.

Kingston is currently in a run-off with David Perdue of Sea Island for the Republican nomination for a U.S. Senate seat for Georgia. The nominee will run against Democratic nominee Michelle Nunn.

“I’ve had the great honor of representing our state and my home,” Walker, the 1982 Heisman Trophy winner, says in a 30-second spot. “I care deeply about our Georgia’s future. That’s why I wanted my friend Jack Kingston carrying the ball for us in Washington.”

Kingston is a UGA graduate who has lived in Savannah since 1977. Perdue, a native of Warner Robins who now resides in Sea Island, graduated from Georgia Tech.

Walker’s name has come up many times over the years as a potential political candidate himself. But to this point he has steered clear of entering that arena. His primary residence is in Texas, but he has many ties in Savannah, where his sister Veronica lives. He was born and raised in Wrightsville and starred for the Bulldogs from 1980-82 before entering into a long career in professional football.
