Maybe… Maaaaaayyyyyyybeeeee the left voters need to actually show up to vote.
Now everyone is going to say they voted in a presidential election, possibly even a primary which makes them a rarity! Those aren’t what we’re talking about. The right has made it a point to vote on everything even as small as schoolboards so the only people voting in the tiny little races are the right wing rage crowd or the centrists who are being pulled to the right. Yes, the presidential vote matters, but frankly those lower down votes mean a lot more and if you watch how the Republican primaries are going, shows exactly how much power that batch that will show up has over a party.
Thing is, it isn’t “Just vote”, it’s being absolutely active every step of the way. Dunno what your territory is but my state we’re having an absolute route of the ultra-right wing going for every local position with the Republicans national conference funding them, the Dems have considered the entire state a lost cause.
So kinda, yea, it is a pull yourself up by the bootstraps, and anyone else who you can pull up as well because we’re sure as hell not getting help from the top, but it’s either that or sit on our fucking hands and go “whelp”. Remember, whether you like her or not, AOC primaried the supposed “2nd in command” Democrat. If you don’t like the establishment, you root it out from the bottom.
