Levin sounds more and more ridiculous. This tired old ploy of a candidate who’s behind challenging the one with a significant lead to a debate is comical. Of course Cruz and Levin would like to have the audience Trump could draw to Levin’s radio show, but why the heck should he give them that?
The ones behind always want to debate the one who is at the front.
The one who is at the front has not reason to debate the individuals back in the pack.
That is just another rendition of the stragglers trying to make headlines and get attention by criticizing the front-runner.
