To be honest I'm surprised WA isn't that color too. You get about an hour, maybe hour and a half, any way outside of Seattle and you start running into some straight up white power enclaves. Consider in eastern WA and yeah I'm really surprised not the same color lol.
i'm assuming its cuz like the southern states they actually have real life klan meetings & other irl white supremacist friends so they dont need to seek it out online
