I primary when there's someone worth primarying for.
That means at minimum someone who is actually in favor of social and economic equity in the policies they support. Things like UBI, returning taxes to pre-reagan levels, wealth taxes (oh you have to sell some shares to pay the tax so corporate ownership is more widely dispersed in society? The horror!), prioritizing education funding and fixing our public schools rather than selling out the last paltry funding it has to the wall street charter school Trojan horse, bailing out people in difficult times from the bottom up, and actually enforcing tax code from the top earners down, as the winners should pay back to improve the society that facilitated their wealth hoarding in the first place.
I'll show up for Biden and vote for him in the general with a shuffle in my step and a funeral dirge in my heart, same as for Biden last time and Clinton before that.
I am here once again to vote for least worst, not because I have any hope for a better future, but so I can sleep at night using what little power I have for harm reduction, for keeping the water pumps on the Titanic running, still full well knowing the ship will still sink regardless, just a little slower, and people will die without real help arriving.
I do the chore of picking least worst every time in the general. If I cant even actually get to vote for something positive, even in the primary, then wake me in November for my chore.
