Yes, he was a shit show
He severely weakened our standing with the western alliances (Nato, Climate accord, etc)
He emboldened those who seek to destroy the west (Russia, NK, Iran)
He somehow increased the trade deficit with China while at the same time making chinese goods more expensive for Americans. (tariffs suck, but at least you hope they improve trade, nope).
He normalized nationalism and racism in the US for a large percentage of the population
He increased the deficit during even though the economy was booming (not even including covid)
He oversaw a covid response that was the worse in the developed world--resulting in 10's of thousands more dead than necessary
The worst thing he did was lie and lie and lie in order to undermine the confidence in our institutions (CIA, FBI, Elections, The Free Press). This is a deliberate attempt to destroy our country for his own gain.
