I would say there is a big difference between deciding not to get into a debate when you are leading someone in your own party by 50 percentage points as opposed to being virtually tied with an opponent from a different party with whom you will have substantiative differences in policy and position.

If only Trump had won every primary, you might have a point, but Trump lost Vermont and DC, so I think you are just making excuses.
