RE: "(Black males would apparently like to work more. Nearly 20 percent of black males under 30 voted for Romney, more than three times what McCain got.)"
What's missing in Ann's analysis is the absolute number of black males under 30 who are eligible to vote. There ain't that many when one considers that a large percentage of them are convicted felons, thus disqualified to vote. The non-felons under 30 are mainly trying to work hard and achieve the American Dream, 20% of whom voted for Romney.
