It doesn't matter what the normies think. The progressives who control the DNC (for the moment at least) don't give a single shit about what they think or do. To them the normies will fall in line the second they've beaten Trump...finally. Once the MAGA brainwashing is stopped people will just "naturally" fall back in the Democratic camp like the good little drones they are. After all the Left is on the right side of history and losing is just something that happens when the bad guy cheats...well cheats better then they do I guess.
This is a holy crusade they're on, Trump is the very face of evil to him so whatever they do, what they say, whomever gets harmed in the path is just gravy to them. Remember progressive hate anyone who doesn't think 100% like they do.
Winning elections is the furthest thing from their mind. They need to stop Trump, the HAVE to stop Trump that's all that matters to them now. They are solely the anti-Trump party, the offer nor want to offer anything else.
In their minds stopping Trump will bring them victory. What the victory entails is kinda...fuzzy as they can't really agree what the end game is but they all agree Trump is the person standing in the way of the great Progressive Utopia to come. Whatever that is.
I truly question what these types of people will do once Trump is gone. They've based their whole world view, their whole moral system and their very personalities on being anti-Trump.
What happens to the hero when there is no bad guy to fight?
