It might not be a terrible idea. The next president and their entire team are going to need to be absolutely phenomenal in order to clean up this administration's messes. Many of the land mines trump has laid haven't even been stepped on yet, and we all know full well that if a democratic president takes over in 2020 they'll have the red-hat wearers blaming them for every mess trump made.
Every single government department is going to have to be rebuilt from scratch. Sure, you might get a lot of those career servants back, but many have been lost permanently, and you're going to have to weed out all of the corruption. The economy is going to be a quivering mess by this time next year. The trump recession was always coming, with or without coronavirus, but because of the virus it's going to be bigger than anyone could have predicted. You're going to have to re-implement all of the regulations he rolled back to let his rich buddies and family lay waste to the countryside for a bit of profit. You're going to have to do something big with health care, because what you have now is the rotting carcass of Obamacare that republicans have left lying in the middle of the road that's not helping anyone. Someone's going to have to clean up all those concentration camps you've got down south too, reunite families, rebuild ICE, and prosecute all the agents who are enjoying getting away with human rights violations under trump.
And on top of all this, you need to start repairing the massive damage he's done to foreign relationships. Sure, most Western democracies have just taken a step back and will be ready to come back once you get rid of trump. But there are others that are going to take decades or generations to repair, if they can be repaired at all. He's burned the Kurds to the point that they've gone and aligned themselves with Russia, he pissed off Iraq to the point that they'll never be the ally you spent 15 years and thousands of US lives trying to build them into, they're buddied up with Iran now, who you used to be civil with, Obama was even able to get them to stop developing nukes, but they're back on the nuke trail and getting friendly with Russia now thanks to trumps diplomatic efforts. Then you've got Afghanistan, where you had the fragile beginnings of a national government, until trump surrendered, gave them back 4000 captured fighters in exchange for nothing, and pulled out of the country, so that'll be back under Taliban rule pretty shortly. America has lost every initiative it had in the Middle East under trump. Then you've also got China to deal with, which I doubt will be too bad, depending on how much worse trump makes it between now and then.
So in terms of strategic moves, it might not be the worst idea from the perspective of the democrats to throw away the next term and strengthen their position, but I doubt they're that smart. There's also no guarantee that there would be a 2024 election.
For those of us outside, it's a great academic opportunity to be able to watch a former representative democracy turn into a fascist dictatorship in real time.
