I feel like Clinton did as expected in North Dakota. Sanders kind of underperformed, because 10% went uncommitted. I wonder why? Could the fact that it was an open primary and the Republicans didn't really hold a public contest (just a convention) lead some Republicans to attend the Democratic caucus and just vote for neither of the two? Sounds unlikely but you never know.
I don't know, I expected North Dakota to be a lot closer than it was. This was one of Hillary's best caucus states in 2008. Sanders ended up doing a lot better than Obama did (at least in terms of the MOV) which hasn't been the case in all that many states outside of New England and parts of Appalachia.
