I think a candidate like Trump should stage his own debate. Lets have some real change for a change instead of the scripted bs designed to protect the current power structure.
That may very happen.
Trump will do this debate, then declare it a fiasco, which it might turn out to be.
He then announces that he knows how to run these kinds of things much better than FOX does.
That statement, of course, will be true.
Then, Trump arranges a new, and better, debate.
His setup then becomes the norm for many elections to come.
