Trump has carefully removed himself from the scum like Ryan .
Lots of split voting .
If you will look back at elections including POTUS, coattails are a force to reckon with.
If Trump gets the nomination, he would be dumb to keep trying to differentiate from GOP. He’s smart, he won’t and coattails will be significant.
You can keep seeing only dire straits and looking the gift horse in its mouth, but pessimism never works in your favor.
