ATLANTA (Reuters) - Herman Cain, a radio talk show host and former CEO of Godfather's Pizza, announced on Saturday his candidacy for the Republican nomination for president.

"We are going to take our country back," he told supporters at Atlanta's Centennial Olympic Park.

The 65-year-old has never held political office. He made an unsuccessful bid for Senate from Georgia in 2004.

Cain worked as an executive at Coca-Cola, Pillsbury and Burger King before becoming CEO and president of Godfather's Pizza. He also served as chairman, president and CEO of the National Restaurant Association.

More recently he has hosted his radio program, "The Herman Cain Show," broadcast out of Atlanta.
