Lee Drutman for Vox:

Some good news came out of Maine last week. Supporters of ranked-choice voting delivered more than 80,000 signatures on behalf of a statewide referendum, well over the 61,123 they needed to get the measure on the ballot. That means that Maine residents will vote in June on whether they want ranked-choice voting.

If news of a state referendum on ranked-choice voting in Maine sounds familiar, that’s because it is. Maine residents already did this once before, in November 2016.

If Maine implements ranked-choice voting, over the objection of threatened political incumbents, it could set an important precedent for the nation, building momentum for a much-needed reform to our broken electoral system. That makes the June Maine vote the second most important election of 2018.
