As for accusing Trump of being a "bully?" He like Reagan is truly the bully thrasher. The vitriolic attacks are always directed at those who try to sucker punch him. Treat him like a gentleman, as Cruz did in 2015, he treats you as a gentleman, back. Tag team him in an insulting manner, as Cruz & Rubio did earlier this year; and you quickly learn he punches back.
No one outside the Trump core supporters are in the Trump camp any more. The Trump version of the Don Rickles show has run its time. It has peaked and is now collapsing. Trump is turning into the very politicians that he railed against.
That is the danger of politics of personal destruction, when that is all you have got. It eventually destroys the people who employ the tactic. Hatred is just plain ugly.
