David Perdue, a wealthy businessman and the cousin of former Georgia Gov. Sonny Perdue, has formed an exploratory committee to run for the Peach State’s open Senate seat.

Should he run, Perdue would be the fourth Republican to enter the Senate race for the seat of retiring GOP Sen. Saxby Chambliss.

“I am truly concerned about the direction of our country, and I don’t think we can solve our nation’s problems by electing another career politician looking for a promotion,” Perdue said in a statement. “That is why I am strongly considering a run for U.S. Senate.”

Perdue is the former CEO of Dollar General. The Perdue cousins now head up Perdue Partners, a global trading company based in Atlanta. Sonny Perdue said in a statement that this is the first time David has been interested in running for public office.

“A few months ago, a respected business leader informed me that he was considering a run for U.S. Senate,” the former governor said of David Perdue. “The passion and concern for our children’s future with which he spoke was inspiring. I immediately knew that he was desperately needed in Washington, D.C.”

GOP Reps. Paul Broun, Phil Gingrey and Jack Kingston are already in the race, and Georgia Republicans expect former Secretary of State Karen Handel to join the field soon. On the Democratic side, Rep. John Barrow announced last week that he wouldn’t run, turning attention to Michelle Nunn, the daughter of former Sen. Sam Nunn.
