its both… as a President, he has only passed a few pieces of legislation, the tax cuts and the infrastructure bill come to mind, and that’s about it. He’s appointed some Supreme Court Justices, but that’s not that much hard work. The rest of his accomplishments have been mainly executive orders and threatening or withdrawing from agreements with our allies.
He notably does not prepare for any meetings or summits. He doesn’t read any briefing if its over a page and doesn’t contain pictures or mentions his name. A record number of his cabinet has resigned. He spends most of his time at rallies as if he’s still campaigning for president and/or golfing at his resort. He treats discussions with North Korea as a real estate deal. He’s not intellectually curious at all, believes in conspiracy theories, never blames himself for anything, and flip flops on every issue even mid sentence. He starts twitter fights with private citizens. He bans news organizations he doesn’t like from his press conferences. He thinks he’s above the law.
So as President, he’s not very effective. A lot of members of his own party don’t agree with him. A lot of what he says (see the Fox News interview) doesn’t make a lick of sense. As a jerk, well.. I’m sure you already know why he’s a jerk.
