This really shouldn't come as a surprise. Newt and Herman have know each other for many years. Newt is a big ideas kind of guy, and so is Herman.
Newt has promised to keep Cain's 9-9-9 plan in the national conversation if he becomes president. I am not sure how much this will help Newt. The wild swing in Florida continues. He and Romney have been trading the front runner status for more than a week now. The latest poll has Newt back on top by less than 1/2 of 1 point.
