FYI, Weather Underground scion Chesa Boudin became D.A. of San Francisco through ranked-choice voting. Yes, the young commie came in 2nd in the election, but managed to be enough idiots’ 2nd or 3rd choice to win the election as the candidates with lower tallies were eliminated. The system works to the advantage of “unacceptable” fringe candidates like Boudin because even if, say, 60% of S.F. voters would never want such pro-criminal radical to be D.A. he can still win by making sure that the other 40% who think he’s okay know about him and at least give him their 2nd or 3rd-choice vote. In a true head-to-head runoff with the 1st place candidate, he’d lose.
According to Ballotpedia Boudin was leading from round 1 and the transfers helped Suzy Loftus to catch up, but not enough.
After Round 1 Boudin was leading by ~8,800 votes and by the final round his lead had melted down to less than 3,000.
