As in, ignorance of popular policies and effective messaging being necessary to win an election?

No, you’re wrong to blame the voters.

Dems could have ran a candidate that appealed to voters, but instead opted for the same corporate shills as always. Dems could have campaigned on massively popular populist policies like paid family leave, raising the minimum wage, or Medicare for all - things which would directly improve the material living conditions of the working class. Their donors didn’t allow them to, and their corruption ensured their obedience. Once again, not learning the lesson, and once again, losing in historic fashion.

Braindead take right here. The US has blocked UN peacekeeping forces from curtailing Israeli war crimes since this conflict began.
