Practically speaking, I probably will too. But Democrats in Washington are no better when it comes to lobbyists, war, special interests (like the banking and auto industries), public education, and a host of other issues.
They don't want to win, they want to use the bogeymen surrounding abortion and race to get donor funds. It's no wonder they get accused of "identitarian" politics, while giving mere lip service to their supporters who aren't rich. The Republican base votes enthusiastically and in a coordinated manner. Democrats can't consistently garner that kind of support because they don't follow through, or they capitulate too much. Or they don't want to, because then they would have to actually enact the policy goals they campaign on.
I hope Biden would step down with these numbers, but barring some kind of medical incapacitation, I would be surprised. I think he has a problem stepping aside, much like Pelosi and Schumer. And the DNC will support him just as last time and with Clinton before that.
I haven't heard about anybody considering it aside from Cornell West, and in the protracted campaign cycles of our times, it's getting late.
