So Montana has been culturally Californicated, too? That would be a good point, but I don't think the influx of liberal people has been the sole responsible for this change. And what do you mean with old working class, Getúlio? Plays it an important role on Montana politics? I assumed that Montana had little working class people, since the state's industry doesn't seem very prosperous.
And actually mormons stand around 5% in Montana, maybe insignificant if compared with Utah or Idaho, but for someone who is not used to see non Catholic Christians, it's a really remarkable percentage
