The one person I believe Trump will be running against was not on stage, and ultimately will escape all this intra-party debating is HR Clinton. When she finally announces she is running, she will avoid the entire clown car. And I believe it is a well crafted, choreographed strategy for her to run again.
She enters in the Fall to save the party. She wins one primary after another, and it was all planned this way to contain Sanders.
It will be TRUMP vs CLINTON again
