The (rigged) race isn't definitely over, so I'm a bit early with this, but here's the thing: The biggest problem with a Biden nomination - or rather with Biden's vice-president's nomination, to be more precise - is that it means that the Corporate Democratic Party will not change one iota. It doesn't matter whether Trump is re-elected or somehow Demented Biden gets enough boomer votes, nothing is going to change. Nothing. No progress. Nothing.
What this means, is that the only thing that can be done by people who are serious and understand how disastrous this is, is not to vote for Biden. Either vote for Sanders if he goes third party (which isn't going to happen), or announce that you're going to vote for Trump, and then vote for Trump. And keep doing that, until they earn your vote by proposing the policies Sanders champions.
Biden and the Corporate Democrat machine do not earn your vote, they don't deserve it, don't give it to them.
As usual, Krystal is on the ball:
