I'm in the UK, and the biggest thing in my mind about Trumps presidency, the Democrats fought him everyday, on every issue. It was so bad, the Dems sought their economy to collapse, to folk die from COVID etc.. to get at Trump. The fight against Trump started during his nomination, his presidency, and it's magnified post presidency.
The other thing I've noticed is, throughout the world due to COVID lockdowns, folk are worse off in their pockets due to inflation, cost of living etc..
And have you noticed American Democrats try to brag about how they're better off under Biden's economy? Now, it's either just for political points scoring rhetoric, or they're absolutely thick as fuck. On balance, much more of the latter.
