Sure, but that doesn't mean they don't bring values that don't fit there.
I actually sat next to a woman and her son at a Seahawks game in Seattle; they live in Pocatello, ID but had moved there from Redding, CA a handful of years ago. Some amusing (to me) bullet points from our conversation:
* She wanted to make sure they went to an afternoon game because she didn't want to be in "the city" after dark
* As a reaction to moving to Pocatello, "when we moved to Idaho, I thought WE were conservative, but..."
* She was successful in her career and her husband was a stay at home dad and had difficulty meeting people/making friends as someone not in the workforce and who didn't 'fit in' to the social fabric of non-working folks (Eg, female homemakers).
They might even be more conservative than the average Idahoan, but it's not a binary thing; likely they've got "California values" they didn't even realize they held, but folks in Idaho could spot a mile a way.
The same way (say) cops in populated areas of California might be VERY pro-law-and-order and consider themselves very conservative, but not bat an eye over LGBT issues that might rile up a bible-thumper from the midwest who is otherwise a moderate.
