You can't get people en masse to support you on the message of "Your tangible situation will continue to be horrible, but letting those guys win will cause unimaginably worse horror" cycle after cycle and continue to get them to care, and it is understandable to for them to eventually wash their hands of it, because at the end of the day, voting associates you with this system, and it feels dirty to participate because it makes it feel like you bear responsibility for what a Faustian bargain it is every cycle.

I will keep showing up with a funeral dirge in my heart to vote for the lesser evil and attempt to hold back the bloodthirsty fascist horde yet again without hope for things actually improving, but I'm not the norm. Most sane people will eventually just walk away from it sooner or later because the reality is too unpalatable.
