As our latest newswire describes, voters in six cities across the United States used ranked choice voting for their elections.  San Francisco, California and Portland, Maine were among cities using ranked choice voting for the first time to elect their mayors.

In Portland, Michael Brennan led in the first round and was the strongest candidate in securing votes from backers of defeated candidates, winning with 56% when matched against his strongest opponent. In San Francisco, Interim Mayor Ed Lee led in the first round and also expanded his lead during the count, securing 60% of the final round tally.
