More than 17 years after San Francisco approved ranked-choice voting over the objections of then-Supervisor Gavin Newsom, California’s first-year governor got a chance for some payback, vetoing a bill that would have allowed more cities, counties and school districts across the state to switch to the voting system.

The bill, SB212 by state Sen. Ben Allen, D-Santa Monica, was overwhelmingly approved by both the state Senate and the Assembly. An analysis of the bill found no opposition.

“Ranked choice is an experiment that has been tried in several charter cities in California,” Newsom said in his veto message Sunday. “Where it has been implemented, I am concerned that it has often led to voter confusion and that the promise that ranked-choice voting leads to greater democracy is not necessarily fulfilled.”
