David Rea has this op-ed in the Auburn, Maine Sun Journal, advocating that the Maine legislature pass the pending bills that would use Ranked-Choice Voting. Rea is an educator and author in Boulder, Colorado. He actually argues for any form of multi-choice voting, which could include preference voting as well as Ranked-Choice voting. Thanks to Steve Chessin for the link.
Also, here is a somewhat similar op-ed in The Daily Campus, the student publication at the University of Connecticut. It was written by Gregory Koch.
