Fred Thompson is set for another career change: The former senator, actor, and presidential candidate will be taking over Bill O’Reilly’s radio timeslot in March, according to The New York Times. Thompson’s transition to the airwaves signals a renaissance of conservative talk radio, which is preparing to oppose Barack Obama. Rudy Giuliani was also in talks for O’Reilly’s timeslot, and Mike Huckabee is going to host radio segments for ABC News. Rush Limbaugh, Sean Hannity, Michael Savage, Glenn Beck, and Laura Ingraham all signed new contracts within the past month. Limbaugh’s contract promised him $400 million through 2016.
