I mean in an ideal democracy voting for the party you actually like wouldn’t just lead to the party you hate the most getting more power.
But we're in this democracy, in which the left of Hitler party has to carry the national vote by basically over 50% to get over the system rigged against it electing candidates (i.e. the electoral college).
Everyone's quick to hate on Democrats gaming the system, but the party actually gaming the system needs a lot less votes in order to "win" an election.
I understand moaning about the situation, but doing anything but voting Biden for president in our system is unambiguously helping Trump win.
