Another three-way governor's race that will end with a sub-majority winner has fueled calls for Minnesota to adopt ranked-choice voting.
In 2009, Minneapolis became the first Minnesota city to use ranked-choice voting in about 50 years, and its experience offers some cautions.
The allure of the idea is clear: It has been 16 years and four elections since a Minnesota governor gained office with more than 50 percent of the vote. Ranked-choice voting is a way to get a winner with majority backing, even in a three-way race. Proponents say it allows people to vote for their favorite candidate without fear of helping to elect their least favorite.
Under the system, a voter lists first, second and third choices, with lower choices coming into play only if that voter's first pick is counted out.
But that comes at a cost. Ranking candidates statewide would mean counting votes by hand, as Minneapolis did last year, or spending millions of dollars for machines capable of doing the count automatically.
More would be spent to educate voters. Minneapolis spent 30 percent more than normal in an election year to launch ranked-choice voting, chiefly to count votes.
Ranking candidates in Minneapolis failed to accomplish some of the things advocates promised. It didn't raise participation in the absence of a close mayoral race. Indeed, fewer voters turned out. It didn't swell the number of candidates -- 94 filed for municipal offices in 2005, the last year those elections were held, and 95 did so last year. The same number of racial minority candidates ran for office as in 2005.
Also, ranked-choice voting did not change the order of candidates in any single-seat race. Those who got the most first-choice votes wound up finishing first in the three single-seat races in which second choices were tallied to get a winner with majority support.
