I had that thought about being at the 1905 moment, a few months ago. I was hoping the democrats would win the senate and that it would be the February revolution moment. The parallel is that the authoritarians are completely taken out of power and replaced by the bourgeoisie. I do believe that condition is necessary for the left to take power. People here will argue about Obama having had all the chances to implement the progressive agenda but chose not to. The reality is that most "liberals", myself included, believe Obama tried his best and was blocked at every step of the way by mitch McConnell. Given that belief (again, it's OK to disagree, but recognize that it's a common belief amongst democratic voters), democrats aren't going to abandon the party until they see a more clear opportunity botched by the democrats. If they win those Georgia senate seats, and then fail to pass a progressive agenda, they will be primaries hard in 2022. It's sort of a spectrum though. What if Manchin is then the only needed vote they can't get? We need to clearly see Pelosi and Schumer reject M4A and GND and then the conditions will be ripen for a third party or beating them in primaries.

As for the anti electoralism, there was a lot of money spent on social media disruption to help Trump. I think a lot of the anti-biden voting stuff trickled down from that. We will never know, but it seemed suspicious.
