AUGUSTA (AP) — History is being made in slow motion in Maine where ranked-choice voting faces its biggest test yet.

Democrats and Republicans ranked candidates for governor from first to last in Tuesday's primaries in a system that's sometimes called "instant runoff" voting in 11 local jurisdictions where it's currently in use.

But there's nothing instant about Maine's process.

If there's no majority winner, then the ballots will be shipped to Augusta for additional tabulations. Under the system, last place candidates are eliminated and votes reallocated until there's a majority winner.

If it comes down to that, then Secretary of State Matt Dunlap said winners won't be announced until sometime next week.

Mainers who approved the system in 2016 also voted Tuesday on whether to use the system in November for federal races.
