I think the "I will not accept the results of the election" is a disaster for Trump, and is the nail in the coffin for his Presedential run.
He didn't actually say that. What Trump said is that he would decide at the time whether to accept the results or not. Presumably, such a decision would be based on whether he thought there was fraud.
But, despite the spin, Trump didn't say he wouldn't accept a loss. In fact, I think he said something about keeping us in suspense.
