Check out this article by Nora Ephron in the Huffington Post. From her female perspective she believes that the next president will be elected by white men. She writes:

To put it bluntly, the next president will be elected by them: the outcome of Tuesday's primary will depend on whether they go for Hillary or Obama, and the outcome of the general election will depend on whether enough of them vote for McCain. A lot of them will: white men cannot be relied on, as all of us know who have spent a lifetime dating them. And McCain is a compelling candidate, particularly because of the Torture Thing. As for the Democratic hope that
McCain's temper will be a problem, don't bet on it. A lot of white men have terrible tempers, and what's more, they think it's normal.
