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.
Biden never should have agreed to a debate. He should have asserted Trump's record - both criminal and as president - and said the debate was not needed. But he didn't. Because he's Joe Biden. I'm really sorry we picked this guy but we did. Live with it.
Just listening to some UK based podcasts about this, and there's a strong theory forming that the reason the debate was so early in the election cycle was so that it could be a litmus test for Biden to see if he's up to a second term, and if he failed then the Dems may ask him to retire.
