Remember Nate Silver? He's the guy who got so much attention for accurately predicting (in an eerily detailed way) the results of the last election. He's come out with an analysis of gun owners in the US and going by his numbers it looks like the most well-armed segment of our population is white middle-aged men, who are married with children, make between $50-100k, belong to the Republican party, are Evangelical Christians (but only go a couple of times per yeare, i.e. Chreasters), didn't graduate from college, live in the rural midwest and served in the US military.
I can't imagine that fits anyone's stereotype of a gunowner.
