Any more than "Bill the Cat" is.

There are reports out of Wisconsin (on Balloon-Juice) that 300,000 voters didn't have the proper IDs while the margin was something like 10% of that (the final numbers may have changed).

Bernie damaged Hillary and Trump ran with Bernie's rhetoric (and expanded on it).

But given that the polling in the important states was off by 4-5% or so, it's hard to see that any Democrat (or even Bernie, since he's not a Democrat) would have not also been very unpleasantly surprised. Investments are based on the poll numbers....

Polling is broken. Voter ID laws depressed the vote in too many important areas. Relentless "OMG!!1 e-mails!!11" stories and screaming about "Hillary's Corruption™" couldn't help but depress her turnout and swing the late deciding "undecided" people.

It would be good to know more about the exit polls that show Donnie winning the white women's vote - how on Earth did that happen?!?!?

FWIW.

Cheers,
Scott.
