This link is to the exit poll results at CNN broken down by sex, gender, age etc. The obvious conclusion from examining these results is that older women turned out in larger numbers to put Hillary over the top. They want the first female President.
It will be interesting to see what happens among black Democrats in the southern states.
Note that, despite this heavy tilt among older females who had a large turnout, Hillary won by only 2% over Obama according to this morning's numbers. Remember also that Hillary was heavily favoured to win New Hampshire prior to the Iowa results. The surge in the polls post-Iowa may have actually cost Obama victory in New Hampshire because it no doubt contributed to the heavy turnout of older female voters.
I nearly split my sides laughing when I read this headline in the New York Times today. Here's a guy who took the US from a surplus when he took office to a situation where it is now hundreds of trillions in debt, numbers we can't even comprehend. And he "admits" that the economy "faces challenges". What Fantasy Land is he living in?
