MISTAKE.
His claim to presidential legitmacy and the allegiance of Americans is too new and too fragile.
If he can’t make it within the established framework... he shouldn’t be running.
I think he CAN make it as a traditional nominee and if he wants to be a third party candidate, that says he’s not confident in himself. It will be a weak move that looks like and IS a mistake. Hang tough Donald!
He should see the commercials against him first.
