Why did Pierce and Clark go for Hillary, while King and Snohomish went to Obama? They're all large suburban counties.
Thanks for the map Meeker
Pierce County can be pretty much divided into three areas: Tacoma, South Sound, and Eastern. Tacoma is the only overwhelmingly Democratic area, and they went heavily for Obama. The Eastern area is very rural and basically prime Clinton country. The suburbs seem to be good Clinton country to me except for perhaps Lakewood which went heavily for Obama. All in all it adds up to a narrow Clinton victory.
Clark I don't know enough about to say for sure, but I'm fairly sure it's a similar dynamic of Vancouver being an urban area that went Obama, a suburban area that split, and then a rural area that went to Clinton.
Snohomish and King are similar, only the urban area in those two make up a large percent of the population.
That's my basic take, Alcon may have another idea
