AUGUSTA, Maine (AP) - Maine is set to become the first state to allow voters to rank candidates in a general presidential election.
Democratic Gov. Janet Mills said Friday she'll allow such a bill to become law in January without her signature.
The legislation requires ranked choice voting in presidential elections and primaries.
Mills' office says ranked voting won't be used in a planned presidential primary in March 2020. But future presidential primaries would use it.
Under the system, voters rank three or more candidates on a ballot in order of preference. If no candidate gets more than 50%, the last-place candidate is eliminated.
The second-choice votes of everyone who ranked that candidate first are allocated until someone receives over 50%.
Mills says ranking could empower voters. But she expresses fiscal and logistical concerns.
