His twitter account was his most powerful weapon, he had 89 million plus followers.
His presidency was a giant trolling/obstruction affair but his performance during the pandemic was horrific. I am more annoyed at that than everything else combined. The Jan 6th riot and attack on the Capitol was the second thing I have an issue with.
I am fine with Biden as president, prefer him to Trump but I strongly disagree with their association with the re-branded neocons, and their stupid desire to fight a war with Russia. The Democrats are on track to create a generational cold war II, have nuclear confrontation, and spend trillions fighting Russia like we spent trillions fighting in the middle east.
IIRC Trump was one of those anti-NATO conservatives and wanted to pull the US out of the alliance, de-militarize, and leave Europe to fend for themselves. As the situation in Ukraine escalates that could serve American interests if the Russian mobilization is successful and they win the war. And if the Russians win the war regardless of US funding then they will turn into an even more dangerous, fascist and militarized state. They have already increased their defense budget by 80%.
Winston Churchill was seen by the British as being a good wartime leader (and even his failures, many of them serious were ignored) but after they won WW2 the British people, in particular the working class completely rejected him despite his role in the victory. Churchill was the leader to have for war and not for peace.
Since COVID-19 is mostly over, maybe Trump having a second term would be overall better than Biden having a second term, I don't know. If Biden didn't screw around with nuclear Russia and pretend that they are not highly dangerous I would prefer that he get that second term.
