Sanders needs MA as well as OK.
Again, I dont get the Sanders appeal in OK...do rural whites really like him that much?
I have no idea why he has so much appeal. I'm guessing Oklahoma thinks Hillary is a criminal and wants a fresh face, I really don't know.
White rural voters don't like urbane cosmopolitanism, which Hillary and Obama personify and which Sanders rejects. The tend to be economically struggling and very concerned about their personal finances and not at all concern about what Ezra Klein or Paul Krugman think. Hillary's "stay the course" messages falls completely flat with them. Moreover, they find her emphasis on issues like foreign policy, gun control and immigration to be mystifying.
