GOP-dominated suburbs

White flight away from urban areas; combined with the fact that Republicans core base is well-off, married, white, religious families, pretty much explains most conservative suburbs.

In the Seattle area, the conservative areas are traditionally Auburn, Bellevue, and Mercer Island. Lots of well-to-do tech workers who try to avoid the taxes of Seattle itself. However the conservative hold has been slipping there, at least federally, as social issues become more of a deal-breaker.

Worth nothing that most of Milwaukee's police department is made of officers who live in the WOW counties. Which helps  explain why most of them are racist pricks who are terrified of the citizens in the City they're supposed to serve.
