Latinos between the ages of 34 and 65 went for Obama by about a 70-30 landslide margin. That's a little better than Romney's tally among White men and women, just under 60-40.
There were many more Whites than Latinos voting, but that margin is dropping and when you add in political active Blacks and other minorities the delta shrinks
According to a pre-election study by the Brookings Institution, the percentage of eligible White voters has shrunk from 76 to 71 percent just since 2004. Five percentage points in eight years and there is no reason to believe that arc will change any time soon.
Did the GOP nominate the wrong guy? I don't think so. But the primary process did provide ample ammunition for Democrats to remind their voters (or potential voters) that the Republican party did not represent their views.
In the past two elections Republicans have nominated at least four candidates for the U.S. Senate that resulted in what should have been easy wins to losses: Delaware and Nevada in 2010; Missouri and Indiana in 2012.
If the Senate comes back on January 3 with an effective 53-47 Democratic majority, you can see how important those kinds of mistakes can be: It should have been 51-49 R.
The Tea Party which began as a purely anti-deficit, anti-spending movement has morphed into demanding fealty to its fiscal and social policy positions.
The "right wing of the Republican party" has become a redundancy. It now IS the Republican party and there simply aren't enough voters who agree with all of the Tea Party doctrine to win a national election.
The future of the Republican party is in the hands of the Republican party.
A larger and larger share of a smaller and smaller market is no way to win an election, much less win the future.
