Per his campaign, Mike Huckabee today sent a letter to Fred Thompson, inviting the former Tennessee senator to debate. "I am aware of your comments on Fox News that you would like to participate in a series of Lincoln-Douglas styled debates. I would like to officially accept your offer," Huckabee says in the letter. "I agree that what is needed is a real discussion by the candidates about their vision for the future of our country."

"Senator, let's lead by example and get the ball rolling," Huckabee adds.
