The state of Maine implemented RCV for the first time in 2018, and did not see a significant increase in voters making ballot-marking errors. Instead, 90% of Maine’s voters reported their first experience with RCV as “excellent” or “good”. Nationwide, a 2016 study showed that, among 26 cities using Ranked Choice Voting, the adoption of RCV was not associated with any change in the number of overvotes, undervotes or spoiled ballots in those places that used RCV ballots.
