I think that’s an unrealistic expectation you are having for progressives.
That’s like asking Tea Party people not to steal GOP votes! Run only against democrats!
Seriously, will any blue districts vote for a tea party candidate over the lamest dem? Not likely.
We can’t blame the existence of tea party on dems. It’s existence is due to GOP not being extreme right enough.
Likewise, progressives exist not because of republicans, but because dems are not going left enough.
However, if progressives continue to fight for the working class successfully , who knows, we might be able to win some blue collar conservatives over. Also perhaps some Texans would now appreciate some of AOCs donations and not want to return her money like some democrats.
When Biden does a good job, credit will be given to where it is due. Progressives don’t just blindly hate dems okay?
