With 16% of the vote in in Michigan, Bernie Sanders is actually ahead of Hillary Clinton, 51-48. That's... highly unexpected. Big question whether he can sustain it; probably not, but this should be a romp for Clinton. That it's not suggests that - well, let's be honest. Nobody's really happy with their choices or their frontrunner on the Democratic side these days.
PS: Note that AoSHQ Decision Desk called Michigan for Hillary Clinton. The usual reason: the places that remain are going to be the places where Hillary Clinton will do well enough to make up the difference.
[UPDATE: Sanders still ahead with about 41% of the vote in, surprisingly.]
[UPATE: Sanders still ahead at about 80%. So when does he lose this thing, anyway?]
