Forget the polls for a minute. In 2012 53% of voters were women. Obama beat Romney with them by 12%. And that's one of the least offensive old white man possible. Get ready for a 50% margin for Hillary vs Trump.
Before we even discuss swing states, other demos, money... it's over.
But for fun, continue reminding yourself that Hillary will also have enormous margins in every group except white males with a high school education or less.
