Eric Maskin and Amartya Sen NYT oped:
A great deal turns on Tuesday’s primary elections in Maine. For the first time in America, ranked-choice voting — a system likely to reduce political polarization — will be used to choose candidates for governor and Congress. And the system itself, approved by Maine voters in 2016, will also be on the ballot, as a referendum. If voters rescind it, Maine will return to the prevailing system in this country — one that often elects leaders who lack majority support, and turns off many citizens.
