I highly recommend that if you are interested in Oregon, you spend a weekend in Portland or Salem. The city of Portland has the most influence on where the entire state is going. I have spent a lot of time in Oregon due to the fact that half of my biological family lives there. Both Portland and Salem are infested with Libs. The rest of the state is fairly conservative but they don’t have the votes to do much. I see Oregon being very similar to California in a few years.
Unless things have shifted greatly over the past 20 years, Eugene is a lot worse than Salem (politicians excepted). Otherwise, I think your analysis is too optimistic—far more than having the most influence, the liberal areas have control. f you look at election results on close ballot initiatives, you can see a pattern of a few populated counties outvoting the rest—the Portland area and Lane county swamping the others.
