I will preface by first mentioning I am biased as I am a conservative.
Any state that has implemented RCV have nearly universally shifted left, in terms of their politics.
Alaska: Mary Peltola elected over Nick Begich and Sarah Palin (two conservatives)
Maine: Bruce Poliquin (R) won the election however did not have enough votes for a majority. At the end of the day, Jared Golden (D) won the seat.
There's probably more examples but the first is the one I found quickly on Wikipedia and the second is what I can remember from memory.
I also encourage people interested in disenfranchisement wrt RCV to look into the "Ranked Choice Education Association", rankedchoiceedu.org
