Trump grabbed the low hanging fruit in the primaries. Whether he adds to or loses from this base will not make him competitive in November.
A Trump Candidacy is unbelievable to begin with and is only made possible by a very weak Republican Party. A Trump Presidency is completely unfathomable.
Some Republicans would have you believe that he can reset, or turn the corner. This is not a pin ball machine or a recuperating patient. He will attempt to gain traction by lying about some event, history or position, but in the end he will fail.
The die is cast. The last thing I would want to do is to jinx the outcome, but he has been a disgrace to Republicans, Americans, and all allies around the world.
