Oh fwiw, I agree with your parent comment completely. It's just fairly self-evident that the majority of progressive voters are young, which is a demographic with turnout issues, historically. I think progressives both think that people who think like them are more numerous than they are (which is likely a bias of all citizens, if I had to guess) and that they have fairly unique issues with turnout given their age group. Either way, they have to adjust if they want to actually win or achieve anything on their own. Until then, they're gonna have to rely on those pesky pragmatic party politicians they hate so much.
