Tie? It's beginning to look like a clear win. NV, MA, MI - Sanders' three most impressive performances. Win/Lose doesn't matter, but Win is good, of course. They are all states with Big Machine politics writ large across the party. If ABC's exit polls are to be trusted, upwards of 70% of the voters in the MI primary are mainstream Dems. Turnout is down(? they say). This is breaking a few models that Hillary was counting on.
It's beginning to look like Hillary's got a lot more unfavorables in the Midwest than they were counting on. And it's also looking like Bernie should've at least contested to grits 'n greens states. A little more credible performance in the deep south and he'd be sitting even prettier.
But a win in Michigan changes the landscape, completely.
