1) Yes, Biden is not Trump, and that's all I need. Americans voted him in as a vote AGAINST Trump, and as far as I'm concerned, he could do absolutely NOTHING as President (but he is actually accomplishing quite a lot), and I would be satisfied with that. Trump was and continues to be a serious threat to our Democratic Republic, and that is paramount to anything else.
2) Yes, Trump supporters are out of their minds. Every single one of them, and it doesn't matter what rationale they use to support him. He's a serial liar, a criminal, an autocrat, and he doesn't follow the rule of law or respect ANY political norms (and no, that's not a positive). He invited and incited insurrectionists to overturn a fair election, and now we find out he STOLE classified and Top Secret documents from the Federal Government, and not accidentally...willfully. Biden would not and will not ever do those criminal things.
3) There were fewer American jobs when Trump left office than when he began, the first President since Herbert Hoover for that to be the case. The unemployment rate was MUCH higher when he left office than when he began. He cozied up to dictators around the world and fell in love with murderous dictator Kim Jong-un. Biden, on the other hand, has managed SEVERAL significant pieces of legislation that does everything from lowering prescription drug prices to actually supporting our veterans. Oh, and on his priority and order, we took out al Qaeda leader Ayman al-Zawahiri. If you're going to counter with high inflation and gas prices, don't bother. Both were global issues, and both are now falling. Gas can be had for under $3 a gallon in MANY states now, and inflation is dropping as well...along with record low unemployment.
