After the Minnesota Supreme Court ruled ranked-choice voting, also known as instant runoff voting, constitutional two weeks ago, the St. Paul City Council elected Wednesday to have its residents weigh in on the system this November.

According to the Star Tribune, the St. Paul council is following through on a promise made last year to ranked-choice voting supporters that, "if the method was deemed constitutional in Minneapolis, the council would put it on the ballot."

In ranked-choice voting, voters rank candidates in order of preference. If no candidate gains a majority in the first round of counting, the candidate with the least amount of support is dropped and their second-place votes are added to the remaining candidates. The process continues until one candidate breaches a threshold.

Ramsey County Elections Manager Joe Mansky said the system has potential problems, including higher costs and lack of certified voting equipment.

The method would be used only for City Council and mayoral elections. St. Paul voters will have the chance to vote on ranked-choice voting at the general election on Nov. 3.
