I have no idea why Trump regularly engages in outrageous attack hyperbole, it is a part of his established brand and persona. It is who he is. He has a severe problem with impulse control. He feels the need to immediately lash out and attack anyone questioning or seemingly slighting him. Carefully worded and measured responses are required from someone wanting to be the leader of the greatest and most powerful country in the world. Personally, I choose the Ice Lady over the Hothead for this job. Hillary is a study in control and discipline, so much so she is criticized. And while a polished politician, always applying spin, I find her more honest and trustworthy than most. Nearly all politicians sometimes stretch the truth. Trump seems to make a regular habit of it and often in a very clumsy way, Hillary only occasionally and much more artfully(check the nonpartisan fact checker sites). Self control to me is a more serious issue, something Trump is clearly lacking.
