Are you saying that those votes were a critical factor in the election results and yet the Democratic Party did absolutely nothing to try to win their vote? Speaking as someone who voted for Democrats down ticket as the least bad option, that sure sounds like a dogshit campaign strategy to me.
So where's the anger at the people who ran such an utter failure of a campaign? Feels like that's probably a more productive target for your ire. Or is it your strategy to browbeat millions of individuals until they vote for people who can't even be bothered to pretend to give a fuck about them?
