No. They didn't.
In the nine battleground states that decided the election where extensive exit polling was done on November 6th, 0bama lost the oldest demographic (65 and over) by the largest margin: by a whopping 18 points. He also lost the 45-64 demographic by a hefty 9 points.
The national numbers aren't as complete because exit polling isn't done to nearly the same extent in "safe" states, but they show similar results.
Incidentally, he also lost among Whites by an enormous 22 points, and he lost married females.
This election was entirely about dependency: poor minorities, middle class blacks overwhelmingly employed by the government, and single females. Even among young whites (18-24), 0bama did not perform significantly better in this election than past Democrats.
Please don't believe that driving past some idiot blue hair is evidence that old people voted for 0bama.
They didn't.
Oh, and just one more thing for people who’re guided by their prejudices rather than statistics or science: Romney had one of the best Republican showings in recent years among Black males. This is a group that doesn’t vote in nearly the same percentages as Black females, but among those who did, Romney got almost 30%, compared with nearly 0% from Black women.
If Obama does a gun grab or bypasses Congress on the debt ceiling, the term "Battleground" states will likely take on a new meaning.
