Trump has already beaten Cruz and beat him pretty easily spending much less money. Cruz can't win the nomination honestly. Trump can. There is absolutely no reason to debate because there's no reason for a debate. Cruz has already lost.
I have come to the conclusion that there is not much honorable about Donald Trump. He got in the race and took his chances like every one else. When things were going his way he was sort of decent, but when others especially Cruz began to gain on him he started with the name calling and slandering and screaming and buffaloing his way through the debates and just literally ruining them for those of us who had tuned in for information. And when Cruz called him on it, he ADMITTED he was just saying it because Cruz was rising in the polls. If this was a bicycle race, he would be riding with a stick to poke it in their spokes when they try to pass him.
