Yes...But Trump never once ever claimed to be a statesman...just a businessman and a successful one at that. His television show "You're Fired" wasn't a joke about his demeanor. And if you actually ever watched it you would see his behavior and demeanor coming through easily. He usually is cold and calculating and doesn't need to get upset. Sure he gloats...and is boastful but he is effective and does what he sets out to do.
He is very accustomed to answering to board of directors and other investors on a regular basis by giving demonstrated accomplishments of tasks set before him.
Which infuriates Democrats to no end in an atmosphere of oppositional politics.
