Setting aside that you know nothing of my voting history, this is entirely irrelevant.

The Democratic party used to be what the Republicans are today. Eventually they became the party of FDR and the new deal. Now they are the party of Bill Clinton and third way neoliberal corporatism. Things change, and we can influence the direction of that change. Forcing Biden to the left has made him a better president than anyone on the left expected. He’s still not the president we want, but we shifted him in the right direction. The Democratic party as a whole is better now than it was 10 years ago.

Go ahead and piss on the progress that’s been made, but then be prepared to explain how third party movements have done any better.
