I'd like to know this too (and I can't tell if it's in the article, because paywall). RCV (or any other system) at the state level is irrelevant, even dangerously counter-productive, since the electoral college is still FPTP in the end. You get just as much of a spoiler effect. I wonder if this is why MA's bill this year specifically excludes RCV use for the presidential election.
Technically I suppose a state elector from a state with RCV could decide to cast their vote as though RCV were in effect? But that seems unlikely and unreliable.
I disagree that it's counterproductive or irrelevant anyway. In the near term it's inconceivable that someone that isn't R or D will win Maine even with RCV, it will solely allows voters to additionally indicate support for a third party without spoiling their major party preference.
Basically I'd only expect it as enabling the the Libertarian or Green party to start challenging the majors after 20 years of iterated elections, which gives plenty of time to deal with the perceived issue of Maine voting Libertarian instead of Republican and a Dem winning by 1 electoral college vote (which seems an anyway implausible result).
