The scamdemic was his greatest failure for sure. I don't think he would have done the federal/military mandates though. The thing is, he's not great at all. He's just slightly better. He's anti-war. JFK showed you can't be slightly better. They're all hacks and criminals all the way down.

I frankly dont care what he said about mandates. He says lots of things then does opposite. Besides, He authorized a military operation targetting civilians. He's not anti-war. He threatened NATO members in order to strengthen NATO. He sent weapons to Ukraine. He droned civilians. He attacked Syria. He assasinated the Iranian general who was taking out so-called ISIS members which is factually aiding the enemy. He continued the wars. How exactly is any of that anti-war?
