Yea I agree with all that.
I think lots of folks on here agree with something like the general premise of a national day of primaries, probably something like automatic voter registration, expanded voter rights, better standardization of voting practices, early voting, maybe even something that looks like ranked choice.
My guess is if we had ranked choice Sanders would be more popular on aggregate. His ideas are more popular than Biden's on the whole, but people prefer the safety of Biden, so you may see lots of people picking Biden 1 and Sanders 2 or 3.
And I guess the point of continually harping on these things isn't that I don't want Biden to win or I want to depress turnout (lol), it's that I think the best ideas should continue to have a voice. It won't be Sanders in 2024, but I'm hoping there will be some in the party, probably some already regretting coalescing around Biden, who see work stoppages at Amazon and Instacart and get inspired about labor power, some who see Kamala Harris and Joe Biden pushing for free Coronavirus treatment and vaccines but not for any other kinds of financial relief for medical debt or people unable to pay for treatments for other conditions and say "that doesn't make sense." The New Yorker article articulated a lot of reasons why we're barreling towards apocalypse, and if 2020 isn't the year for significant reform, if we need 8 more years to steer us out of the gutter, fine, but I'm happy with the groundwork being lain for real social change.
