Start by supporting the RCV ballot initiative going on in Oregon this November. Donate and volunteer even if you’re not in Oregon. If we’re lucky Oregon will approve it and show everyone else both vote by mail AND RCV works perfectly fine.

lol specifically banning RCV is on my states ballot this November, we won’t be able to do county by county in Missouri if it passes and they’ve tacked it onto some anti absentee vote nonsense so it’s probably going to pass

I’m skeptical about complex voting systems, simply because they cause a lot of confusion and some people don’t understand what they’re voting for.

Here in Germany we get two votes for the Bundestag, it’s essentially a split between district vote and federal vote. The system is pretty simple, you get two columns, one with people, one with parties. And many voters still don’t understand the implications of it.

My city’s council has such a stupid voting system (multiple votes, multiple districts and parties), that it took me and my friends (all having masters degrees or doctorates, one literally being a pol sci teacher) several hours and an absurd chain of local/state websites to finally find a Word(!!) document that somewhat explained the process, and we still don’t really know what was happening.

My point is not that 80% of people are too stupid to understand these systems, but too lazy to look for information, and that’s fine. Even the stupidest voter should be able to find and understand the system within 5min. If not, information is obscured or the system too complex.
