(CNN) – Herman Cain's taking to the air waves again.
The former Republican presidential candidate will fill the spot left vacant by retiring radio host Neal Boortz, who announced his decision Monday on his program.
January 18, 2013 will be the last day of "The Neal Boortz Show," which premiered on News/Talk WSB in 1993 and can now be heard on more than 200 radio stations nationwide, according to WSB.
Cain, who currently joins Boortz daily for a segment, will host his inaugural show on inauguration day, January 21, 2013.
Cain previously hosted an evening program on the radio station and jokingly thanked the over four decade long radio veteran Boortz for keeping his seat warm.
"Also, I am ecstatic that Neal has kept the radio host's chair warm for me all these years," Cain said in a statement. "He may be 'The TalkMaster,' but Neal's listeners know I'm the 'The Dean of the University of Common Sense.'"
The former CEO of Godfather's Pizza made a tumultuous run for the Republican presidential nomination last year, a bid that ended in December amid accusations of sexual harassment.
Boortz, known as the "The Talkmaster," said he plans to spend time traveling with his wife after his retirement.
"Believe me, this wasn't a decision I made lightly. I love this business and everything it has afforded me," Boortz said in a statement. "I'm grateful to have had the opportunity to be doing my talk show for 42 years."
