He was handed the reigns of the pretty stable and steady Obama-era economy and by the time he left the US economy was in fair shambles.
Which was, of course, significantly caused by a certain global pandemic that he outrageously mismanaged.
Hard to say what would've happened absent COVID. There's plenty of precedent of the cycle of neoliberal Democrats getting the economy all roasty toasty then losing an election to a Republican who immediately puts out huge tax cuts for the extremely rich that is followed quickly by some kind of financial crash.
There is an argument that the Trump Administration was the cause of the global pandemic by recklessly dismantling healthcare watch teams in China and not acting to close U.S. borders when the outbreak occurred.
I believe that for the next 400 years the worse insult that politicians can throw at each other will be to say that their opponent is like Convicted Sex Offender Treason Trump.
...audio from Trump advisor, Steve Bannon, surfaced from October 31st, 2020, just a few days before the Presidential election.
Let's listen. [Begin Videotape]
STEVE BANNON: And what Trump's going to do is declare victory, right? He's going to declare victory, but that doesn't mean he's a winner. He's just gonna say he's a winner. The Democrats — more of our people vote early that count. Theirs vote in mail. And so they're going to have a natural disadvantage and Trump's going to take advantage — that's our strategy.
He's gonna declare himself a winner. So when you wake up Wednesday morning, it's going to be a firestorm. Also — also if Trump is — if Trump is losing by 10 or 11:00 at night, it's going to be even crazier. Because he's gonna sit right there and say they stole it. If Biden's wining, Trump is going to do some crazy shit.
It is for these reasons they are enacting laws distasteful to libs, like abortion restrictions, anti-LGBTQ, so as to purify their state and retain what dying power they have.
