White women

Everybody always talks about Obama's "black vote" primarily because of the overwhelming disparity in support, but Clinton's key demo, Democratically registered white women has really played a bigger role in the numbers.

Per the exit polls, 47% of the Pennsylvania Democratic electorate last night was made up of white women, higher than any other race/gender subgroup. Clinton ended up winning them by more than 30 points, 66%-34%.

Think about that. Assuming the rest of the electorate splits down the middle 50/50, Clinton wins Pa with a +15 overall advantage coming from this one group alone.

That's not to discount these voters, but, as a point of analysis, it's interesting.
