Something striking is that on the Nynorsk Wikipedia page for Framstegspartiet, the logo in the infobox nonetheless reads Fremksrittspartiet. The implication, I guess, is that no FrP voters use Nynorsk anyway, which seems like it might be accurate. Either way it's amusing.
There are areas where both FrP and Nynorsk are relatively strong, most obviously Møre og Romsdal, which FrP carried and which is one of a couple of counties where Nynorsk has been officially adopted by the county. I don't know what the explanation is for FrP's strength in that area.
I'd guess the most overrepresented party among Nynorsk users is Centre, though.
