If you take what Trump says and tweets at face value you're going to be in a state of continuous emotional torment. It is pretty well all an act designed to antagonise the US media. They oblige because there's a mutual benefit pact between the "fake news" media and Trump. He rallies his base because he's always under attack, and the essentially Democrat media makes money out of covering Trump - bad news appears to sell well.
The legislation he's actually got done is not that bad. His trade deals are reasonable from a US perspective (Not great for anyone else but better than what they had). The First Step Act helps minorities who leave prison to find work. He's organised training for displaced workers. And he's arranged for paid family and medical leave for Federal employees. Add to that the fact the US has pretty well full employment, that the working class has seen a vast improvement in their income, that death by suicide by opioid addicts is falling for the first time in years and if you're an independent voter faced with the choice of losing your health insurance under a Democrat President or facing another 4 years of rising wages under Trump, it's not a difficult choice. My guess is most will hold their nose and give him four more years - assuming the Corona virus doesn't kill the US economy.
Trump isn't a threat to democracy. The US is an enormous bureaucracy largely populated by Democrat appointees at the top levels. Trump has managed to implement a few policies, but anything that requires the state apparatus is off limits. He can't even hold a meeting in the White House without it being leaked 5 minutes later if there's even the slightest chance of it being perceived negatively. And he can't do much that requires money without getting it approved by the Democrat led House of Representatives. Even when the Republicans ran the House they wouldn't do what he wanted. That's why the US constitution is set up with a division of powers - to stop any one part getting above its station.
Foreign policy wise Trump is a lot less dangerous for the world than was Obama. This may not seem to be the case at a subjective level but the numbers bear that out. He's avoided foreign wars and he got elected in part because he promised to bring the troops home (only partially successful so far).
He's an unpleasant person, but then do most of us really like our politicians? Ironically with a few months to go before the election Trump is now more popular than was Obama at the same time in his first time in office.
