"Progressives should not make the same mistake that Ernst Thälmann made in 1932. The leader of the German Communist Party, Thälmann saw mainstream liberals as his enemies, and so the center and left never joined forces against the Nazis. Thälmann famously said that ‘some Nazi trees must not be allowed to overshadow a forest’ of social democrats, whom he sneeringly called ‘social fascists.’
After Adolf Hitler gained power in 1933, Thälmann was arrested. He was shot on Hitler’s orders in Buchenwald concentration camp in 1944."
The delusion is thinking you can change things with a single election. If you don’t like the two party system (and I don’t) then you must get more involved in politics than voting for the president. You would need to elect principled progressives at every level of government, fight against fascism at every opportunity, and diligently protect the progress we have made.
Voting for a third party candidate is like showing up to a birthday party as they’re lighting the candles and complaining that nobody asked you about the decorations. It doesn’t matter if your objections are valid, you’ve missed the window to do anything about it.
