It is dirty tricks and you know it, but that is OK. I am glad they did it. Biden is a way easier opponent for Trump than Bernie. You keep falling for conventional wisdom and we are beyond conventional wisdom in our politics.
The groups the democrat party need to win are on the fence. Nobody is enthusiastic about Biden. It isn't even debatable. You will convince yourself (like you did with Crooked Hillary) that he has a strong following, but he doesn't. Like you said, this was all orchestrated. Orchestrated campaigns is what the American people left and right are sick of. There won't be anything to orchestrate in November. Biden has to stand on his own. Biden elicits no excitement. He is a relic of a broken political system Americans are sick of.
I thought you leftists would have learned that lesson in 2016, but apparently you are destined to repeat them. It is fine with me. I am looking forward to four more years of MAGA
