As the Trump Presidency winds down, I actually am anxious to stop even thinking about him because unless something really weird happens, he will stop being relevant.
Biden and Harris have their work cut out for them. Over 70 million people voted against him, and many are vocal about their hatred for him. It looks like McConnell will once again work to make a democratic President a one-term President, and if he follows Trump's lead (and he may have to if his base gets too out of hand), he will go to pretty far extremes to sabotage things so that republicans have things to blame Biden for in 2022 and 2024.
The international reputation of the US is at rock bottom. And the world knows that since we voted in Trump for President in 2016, we certainly can double down on someone like Trump or even much worse in 2024 or 2028. The fact that Trump was not removed from office when he was impeached, and the fact that Trump's attempts to steal the 2020 election have not landed him in jail (or at least forcibly removed from office) are two huge strikes against the US and reasons for the rest of the world to keep us at arms length.
The virus will be very bad by the time January 21 rolls around. The vaccine might be all that it is cracked up to be and the virus might just disappear. Or, it may turn out that the reason that the CDC is trying to get blacks and other minorities to get the drug first is so blacks and minorities will be the guinea pigs to resolve any remaining issues rather than whites. The virus is a huge wild card for 2021, and if you were to predict the number of daily cases in the US next September, on the low side would be ... well it could be zero, or single or double digits, and on the high side it could be 5k deaths a day. Makes it a bit tough to plan things. Biden / Harris will have to be very flexible in what they say and what they do, and all along a huge part of the country will be looking for things to hate them for.
One thing Trump did a fabulous job of: there are more economic triggers that are ready to explode in early 2021. The current stimulus runs out in a month, and many people will be just plain flat broke in January. Homelessness could very well increase rapidly. Landlords could find that after evicting people that haven't paid rent in half a year that their places just remain unoccupied. Trump really did run the deficit up to numbers that no one thought possible after Obama's term. US companies are decoupling from China by moving production and stay-at-home jobs to Asian countries that are not China. I guess this is an improvement. China is decoupling by creating chip industries and a new internet and a new operating system that will allow them to stop buying things from the US. And oh yeah some of this production will be exported, so instead of buying products from the US, they will be exporting their own products and competing with US companies all over the world. Climate change caused big problems this year in California withe their wildfires, and the Gulf States with so many hurricanes. Climate change is getting worse and worse bit by bit, just as predicted since around the 1980s. With the exception of California and hopefully a few other states, state budgets are very much in the red.
This is a lot of very difficult problems to deal with all at once. And I haven't even listed them all. Good luck to Biden / Harris. They will need it. And we need for them to be at least moderately successful.
