It wasn’t a debate, it was a discussion designed to showcase the two candidates as a team. Herman wants Newt as his veep, that was his likely motive for participating. I would not call it gutsy at all, however, I do believe Cain has proven himself to be a very gutsy man in any case.
They did look like a Presidential team as they waved to the audience after the debate. I would call them a well balanced ticket.
Go Cain/Gingrich 2012
