only because of their gerrymandering manipulation bullshit.
As for the topic, the main reason CA move to Idaho is the same reason they move to WA. Because they can sell their homes in CA and then purchase 2 or 3 of the same in both states for what they sold their home for in CA (live in one, rent out the others), and now with many working remotely, they do it while still collecting the higher wages of CA. It's funny, I have an uncle who moved to Idaho a couple years ago. First year he parroted how much cheaper it is to live there than WA. a year later he is singing a different toon. He now has income tax, property taxes are double what he was paying in WA for comparable land/home, as well as other costs. (fortunately because of his age/income he gets a lot of that forgiven). He even pointed how bad Idaho is when it comes to road maintenance and other services compared to WA...
