Looking at the New Hampshire exit polls we see some interesting data. As you see above, the richer you are the more likely you are to support Romney, and the poorer you are, the more likely you are to support Ron Paul. I suspect the latter fact is determined pretty strongly to age — young people have low incomes and young people support Paul.
Also, 77% of self-described evangelical or born-again Christians voted for either a Catholic or a Mormon.
