I'm not saying it's actually going to happen, I'm just saying it should if the Democrats actually want to win. You're welcome to think I'm delusional or laughably dumb all you want, this was not performing poorly in one debate, it was a mask off moment for how nonfunctional Biden actually is. Doesn't matter that Trump is as old or a convicted felon or worse in just about every way, his following is large and dedicated and not going away and we need every vote we can get. Ignoring that Biden is clearly no longer fit for office in the eyes of the vast majority of the public will make us hemorrhage support in November. If you think that can be safely bypassed and that Biden will be carried back into office off the strength of his "policy success" and incumbent advantage and "appeal to the middle" at this point, good luck and godspeed. You can have some of what I've been smoking but I want some of yours, I think it's stronger!
I feel that ignoring what nearly everyone felt about what they saw and just buckling down with what we have until November not only wouldn't be right - it would chill our voters even more. It would just be another way of announcing the Democratic party's contempt for the electorate, a testament to how completely their electoral strategy begins and ends with "you have to vote for us because we're your only option." And I completely understand your misgivings about an open convention appointing a candidate without a primary. It's not something I'd suggest or want them to consider except under circumstances as dire as this. But I truly, genuinely believe that if it's Biden in November, we lose and lose big and I cannot resign myself to that possibility when it's not technically locked in yet.
