Minnesota: Supreme Court probes the constitutionality of ranked-choice voting

Supreme Court probes the constitutionality of ranked-choice voting:

The legal showdown over whether Minneapolis can go ahead with ranked-choice voting for city elections this fall reached the Minnesota Supreme Court on Wednesday.

Justices signaled that although they find the vote-counting method confusing, especially for multiple-seat elections, they're not sure there's a constitutional flaw in the law. They pressed the law's challengers repeatedly on that point.

Ranked-choice voting -- known in some jurisdictions as instant runoff voting -- was approved handily by voters in 2006.
