A state district judge on Wednesday ordered the city of Santa Fe to use ranked-choice voting in the March election, when voters will choose their first full-time mayor. Judge David Thomson said the ranked-choice software is “clearly available” and must be used in the election in accordance with the city charter amendment of 2008 that authorized the system. “To me, in the end, the concerns [about accurately implementing ranked-choice voting] do not meet the law,” Thomson said.
