Here is what I found interesting:

Obama won the youth vote 60% to 37%.

Romney won the retired vote 56% to 44%.

Obama won the high school graduates (and dominates those who didn’t finish high school) and also won decisively amongst those who pursued postgraduate degrees.

Romney won the college graduate vote.

Here is the kicker:

If your household income was less than $50k, you overwhelmingly voted for Obama.  If your household income was greater than $50k, you likely voted for Romney. Make of that what you will. Santa Claus politics?
