Blacks cast 13% of the vote and Obama won them 12-1. Latinos cast 10% and Obama carried them by 7-3. Under 30 voters cast 19% of the vote and Obama swept them by 12-7. Single white women cast 18% of the total vote and Obama won them by 12-6.
There is some overlap among these groups, of course, but without allowing for any, Obama won 43-17 before the first married white woman or man over 30 cast their vote. (Lets guess that if we eliminate duplication, the Obama margin would be 35-13) Having conceded these votes, Romney would have had to win over two-thirds of the rest of the vote to win. He almost did. But not quite.
If Romney couldn’t manage this trick against Obama in the current economy, no Republican could.Dick Morris, “Why I Was Wrong“
