Every time I read how someone from the PNW denigrates people moving up there from CA, assuming they're all "liberal transplants", I think of the conservative people I've known who moved there from here.
I remember when I lived in Medford for almost a year, back at the end of the 70's, and you could see billboards around town stating "Don't Californicate Oregon" ... except when you talked to a lot of people, it was seemingly a lot of CA retiree's who were bringing much of the local money into the economy, and much of the local PD & SO were transplanted CA cops looking for a better place to live and work.
Now, if a liberal politician moves from CA to the PNW, and finds fertile ground in the local voter demographics (who aren't "liberal transplants"), how is that the fault of CA?
CA has been sending a lot of retirees who can't be painted with the "liberal transplant" brush stroke to the PNW, and even younger people looking for a better life, with more affordable cost-of-living than can be found in much of CA.
You folks don't think that the PNW "territories" originally had indigenous conservative, non-Native American populations without people from other states and territories migrating there, do you?
Look at the huge number of workers being attracted there, and wonder if your boon in some industries (and companies) may not be a mixed blessing, of sorts, and may be the actual reason you're attracting people who may have different backgrounds and social/political views than those born there (or who moved there, but would rather other people forget they weren't actually born there
).
