For years, ranked-choice voting has been little more than a concept. The software didn't exist for the machines used by the state. (New Mexico law requires the same voting machines to be used statewide.) Then, it became an expensive concept, but one that was theoretically possible. In a June 23 memo from City Clerk Yolanda Vigil to city councilors, the clerk said the cost to install ranked-choice voting software on the current machines had dropped to just $40,000. She asked councilors to decide if there was time to roll out the system called for by city law.
