Any Democrats who can stand up and show leadership right now stand a very good chance of becoming the most powerful person in the world. Trump is a deeply unpopular candidate. It won’t take much to expose his weakness for what it is, we just currently happen to have the weakest possible candidate. Swap the candidate, adopt the positions of the base, and whoever ends up being the nominee can coast into office.
I think this is rather obviously true. Many on the left have been pushing for a different, and presumably better, candidate from the beginning, so in a way, all that's changed since the debate is that many more have joined them. So really, all the Dems have to do is provide the people with that candidate, and it'll be a runaway.
BUT...
I'm starting to worry that the DNC is going to fuck it up yet again, and specifically because, just as was the case in 2016 and 2020, they're not only going to not adopt the positions of the base, but are going to instead manipulate the process in order to shove another establishment hack down our throats. And quite likely not even just any establishment hack, but the one that's already proven to be even less popular than Biden - Hillary Clinton.
This is a moment for the DNC to get out of the way and let the people come together and choose the candidate they want. That's the exact thing that will motivate the base, and in turn guarantee Trump's defeat.
I'm just afraid that the DNC won't be able to do that - that in their all-consuming self-centeredness and greed, they're going to fuck it up for all of us, yet again.
