Pulling out of the Paris climate agreement; pulling out of the Iran nuclear deal. Promoting "coal" (as if there were no better option -- even for the coal miners, if the administration had the sense to support another option). Various things about the p******c, such as lying to the public about it, as seen by the contrast with what he had told Bob Woodward. Cultivating a climate of disrespect. Cultivating a climate of ignorance about government, although that didn't start with him. He's just better at spreading ignorance than the other folks are.

All that said, I think it's important to remember that Trump, bad as he was as a candidate in 2016, became president in large part because of the bad workings of the Republican Party. It's analogous to parents neglecting to guard against their child doing wrong things like running into the street or setting the house on fire. There should have been guard rails to prevent someone like Trump from becoming president.

When Trump became president he was unprepared for the job. He was good at being obnoxious; and that (plus inherited wealth) got him pretty far; and then suddenly he found himself in a position he was almost totally unqualified for, and he didn't know what to do.

So it's not totally just his fault. You wouldn't blame a moron for failing a PhD oral exam in something he hadn't studied; right? In that example, much of the blame is on the people who set the moron up to take that exam.

To a large degree, the Republican Party did this to Trump. I'm really glad I'm not Trump: that's what I thought soon after he got elected, and I still think it. In that position (just having been elected president), I (realizing that I was unqualified for the job, and that I had boasted too much) might have died of shame. Trump in public usually appears to have a kind of callousness or shamelessness. I'm sure that callousness is occasionally useful in a president; they have to withstand pressures. So in that one small way, he was qualified, in a tiny partial way, to be a president. It's like a drop (or, just one thing) compared to a bucketful (of a variety of things) of what's needed to be a good president of the U.S.
