From Paul Krugman's home page:
Certainly the heartland has no claim to superiority when it comes to family values. If anything, the red states do a bit worse than the blue states when you look at indicators of individual responsibility and commitment to family. Children in red states are more likely to be born to teenagers or unmarried mothers — in 1999, 33.7 percent of babies in red states were born out of wedlock, versus 32.5 percent in blue states. National divorce statistics are spotty, but per capita there were 60 percent more divorces in Montana than in New Jersey.

And the red states have special trouble with the Sixth Commandment: the murder rate was 7.4 per 100,000 inhabitants in the red states, compared with 6.1 in the blue states, and 4.1 in New Jersey.
Update: Paul Krugman published this information in the NYT a few years ago.
