I've never lived there for sure, but at least driving through a whole ton of the state, it doesn't seem to just be the Willamette valley. Driving through the Umpqua national forest I saw plenty of militia compounds (okay, it was likely only 2, but a ton of people with giant Trump and don't tread on me flags, and a few properties that looked like there were actual above ground concrete bunkers) followed a quarter mile down the road with someone's property with giant LGBTQ+ flags flying, or weed flags, etc. It was extremely schizophrenic.
I'd agree most of the parts east of the Cascades seemed to be fairly conservative, but all of the bigger towns like Bend were very liberal, and plenty of farms I drove by were also flying it high that they were liberals. But that is the case almost anywhere. Rural areas tend towards about 2 conservatives to 1 liberal. Urban areas tend towards about 2 liberals for 1 conservative. And most suburbs and medium sized towns are closer to 1 to 1.
