In this time, when it is clear that Biden will not get in without the Left, and the mentality is "anyone but trump" it is the perfect time to rally behind a revolutionary third party. A Greens/DSA/BernieBro alliance could seriously hold the election hostage. If this is not the time, when the fuck will it ever be? obviously this is not enough, but you can "hold them accountable" way more than you could hold joe fuckin biden and the democrats
Besides everything that has already been said, the Democratic party has made it clear that they don't give two shits about us. Their long term and 2020 strategy is to pick up moderate Republicans and independents. What leftists should be doing is uniting around not voting for Biden and loudly communicating that we won't so that if he loses and we inevitably get blamed we can point to the fact that we clearly were not going to vote for Biden and it's the fault of the Democrats for discounting that. Sadly man leftists feel inclined to support the competent friendly bourgeois party as if the Republicans are the reason America sucks and not the class dictatorship of the bourgeois
