BTW, what is it about SD that favored Clinton in '08 and favors her now?

In '08 she was favored because this was the only Plains state that held a primary instead of a caucus and because she campaigned hard while Obama had already pivoted to the general election and spent his time campaigning in Michigan, Missouri and other swing states.
