Referring to Oregon as a largely white but affluent state is about as incorrect as you could possibly get. And the subtext to this in my mind is, frankly, racist. They're back to using the old pejorative definition of the term "liberal."
Given Clinton's recent major and undeniable race-inflected victories, the increasing charges of sexism, particularly against Obama himself, are misguided at best. This is no way to advance party unity or women's rights.
