They we're invading Idaho in the early 90s. Saw many a bumper-sticker reading "Don't Californicate Idaho" at the time.
It started in Oregon in the 70’s - bumper stickers and signs saying “Don’t Californicate Oregon!”
Now Oregon is just as bad as California - people in wealthy areas of Portland can’t sell their homes because homeless have camped out on the street - or on their lawns. As in California, homeless have more rights than homeowners or average citizens trying to go about their business.
Yes, could be from lefties moving there and then voting as they did in the Golden State.
In the early seventies the same was going on in Oregon. Losing battle.
