Joe, Newt and Rick already did a one-on-one debate in November I think. It’s on YouTube. They both signed on to the Trump/Newsmax debate to debate each other but it was cancelled.
JUST SAY NO TO THE MITTRICK SYSTEM!
Rick and Newt met for a sit down panel...not really a formal debate, just before Veteran's Day...that's on Youtube. At the time, Cain was getting all the coverage, and just starting into his downslide with the lady problems. Neither Newt nor Rick really had any traction at the time and both were glad for the forum. It was just after this time that Newt's campaign rhetoric turned to him following Obama around the country challenging him to L-D debates at every stop. Every second and third word out his mouth was "Lincoln-Douglas." By the end of November/early December Cain was all but done. That's when Rick said, "OK...I think that's a great idea...I'll do a Lincoln-Douglas with Newt in Iowa."
Newt didn't respond to Rick, but was willing to go head-to-head with Huntsman (yes...Huntsman?!?!) in a formal debate about a week later.
Personally, I think Rick should go to GA and debate, but at the same time, he did lay down the gauntlet last December and Newt refused to pick it up. Newt and his supporters have no moral standing to say that Rick is "chickening" out of Georgia.
