Government can be unwieldy, and turning the ship of state can be a herculean task. I wouldn't be so hard on Trump, but his hubris is as insufferable as his ignorance is complete. He campaigned as a fixer with almost superhuman powers. Trump declared that solving our problems would be easy for him.
Exactly, and that's his failure as a leader within a democratic form of government. When you take on something as large and complicated as the president of a democratic nation, you need to seek out and surround yourself with people who are qualified and skilled at specific tasks and give them space, but above all, listen to them.
Donald Trump never had to answer to a board of directors in any of his business dealings. Of course, he would say his five bankruptcies were not his fault. Narcissists are like that, so he surrounds himself with yes-men, toadies, cronies, and loyalists. When things go south, he can point the finger at anyone but himself, even though he may have appointed them to positions of responsibility, qualified or not.
My problem with Donald Trump isn't that I believe he was a poor choice to lead a democratic nation, I simply don't think he's a good person. Authoritarian leadership might work in the reality show world, but it's a bad fit for democracy.
