Maine’s Republican Gov. Paul LePage has threatened not to certify the results of Tuesday’s primary elections in Maine, because the state is using an entirely new system of voting. As Maine voters head to the polls to cast ballots in the nation’s first statewide election using ranked-choice voting (also known as instant-runoff voting) that has left Maine’s other state officials scrambling to figure out what to do next, in the middle of election day. Even if LePage follows through on his threat, there may be other ways to certify the election results.
