Outside of the south, Ohio is the only non closed primary that Bernie lost by more than 2 points. And that might have been because of all the Democrats who voted Kasich. All of Hillary's wins by more than 2 points were in the south, a closed primary, or her 5 point win in the closed Nevada caucus.
These are statements of fact to be sure, but I have to wonder why you chose to single out the 5 point Nevada win as a special case? If the point was that she only wins by more than a couple points in the south or closed contests, Nevada provides a counterexample to that does it not? Also, I don't see why the open contest wins in the south should be neglected in terms of Hillary's appeal, as it is implied. There were a lot of them and they were very big, and they count.
