The voting public is increasingly dominated by Hispanics, Youth and Single Women.
Consider:
* 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.
* Obama won 43-17 before the first married white woman or man over 30 cast their vote.
With the above, Romney would have had to win over two-thirds of the rest of the vote to win.
He did win the rest but IT WAS NOT ENOUGH.
Excellent summary. Bottom line not far off fron 47 percent
Tribalism.
