Trump is a winner. He went after Carson with the media attacks as well because he saw a way to take him down and that’s just what he did. He wants to win. Everyone complains when you have a Romney not going hard and can’t take it when you get a Trump who wants to win. He is saying these things about Cruz because he wants it repeated just enough to slow his train. Do you expect him to just let Cruz win to make Rush happy? Ultimately he respect Cruz which is why these punches were not as hard as a normal Trump hit. We’ll see where it goes from here. As long as their supporters don’t go crazy against one another this will be fine
