All right, I'm going to say this and be done with it. Biden is president now, so is clearly capable of being president. And if that changes, he has a capable vice president and a capable staff. No one else is guaranteed to beat Trump; we need to shut up and vote for the fucker what brought us.
When the choice is between an elderly person with a raspy voice surrounded by dedicated professionals who believe in science & representative democracy and a sociopathic, fascist sex pest who lies with conviction and confidence & will surround himself with rabid jackals...well, the choice is clear.
