Well, might as well post a prediction now and see how far off I am from final result in November.

My convention for this map is that anything shaded lightly blue or lightly red means margin of victory is under about 54/46.
BOLDEST predictions: New Hampshire goes red, Utah goes blue, and that MI is close and not a safe blue.
I still have Arizona, Georgia, and Mississippi going red but not by much. I expect a significant but not quite blowout win for Hillary.
Interesting to see such a broad range of guesses from everyone in this thread so far, literally 200+ electoral vote swings.
