Your whole statement sums up nicely why the Dems CAN blame the left: you "will not be voting for Biden". Even if you abstain from voting for either candidate, in political speak a non-vote is a +1 for your opponent instead of the +2 your vote would have been for the Dems. Looking at this as a third party, you Americans really need to break out of the 2 party system by finding a way to add at least a third viable party, using some version of Ranked Choice Voting or ideally both. Mainstream + Social Media + 2 party system is killing your country.
