@illusionofjoy I live in #Australia: we have Ranked Choice Voting (we call it preferential voting) and I'm a huge supporter.
Coupled with #compulsoryvoting, it generally induces politicians who want to be elected to move to the middle, but it also enables #voters to move the Overton window, because if single issue/small party candidates attract support, then major parties sit up and pay attention, and generally try to adopt policies that will regain support.
@illusionofjoy I've also been a #scrutineer in many elections and the vast majority of votes are cast validly: the ones that aren't are mostly defaced or left blank, so not resulting from confusion.
There are also sensible "savings provisions" so that, for example, if there are 5 candidates and a ballot has one to four on it and the fifth box is blank, it gets counted.
It's also very rare for a candidate not in the top three after first preferences to win.
It's a good #voting system IMHO.
