RCV is no different. It just avoids the expense and headache of running another election. The "refining" thing is an excuse. Same one the Republicans are using. It's like you guys are getting your talking points from the same place.
No, actually, it is a problem, because if you were one of the ones who voted for #3 who was eliminated, you weren't given a choice. The issues may have switched entirely.
Take, for instance, Chicago's recent race. The top four contenders were.
1) Lori Litefoot, the incumbent Mayor
2) Jesus Garcia and his Porn Star Mustache
3) Paul Vallas, the prior School chief. Heavily backed by the Fascist Order of Police (FOP)
4) Brandon Johnson, the former Chicago Teacher's Union head.
Now, Lori unloaded most of her ammo on Garcia, and in a split decision, Vallas and Johnson came up higher.
Simply put, when it became those two guys, the narrative of the race changed from a referendum on Litefoot (who frankly gathered a whole lot of animus because of how she handled Covid) to crime and how to run the schools.
In short, the focus was more down to the vision of these two men, who were now in a sharper contrast because they didn't have to deal with professional clown Willie Wilson
As opposed to NY, where the election was decided by people who checked Adams as their fifth choice and probably never knew what hit them.
