[L]et’s imagine that Hispanic Americans’ demographic positioning looked different. Let’s say they were disproportionately unlikely to have children out of wedlock, and had higher incomes and educational achievement than whites.

By National Review’s logic, this should make them a natural conservative constituency, ready to line up with Paul Ryan and Pat Toomey. But Asian Americans — who do have these characteristics in the aggregate — vote Democratic in roughly similar numbers to Hispanics. This should be a clue that Republicans’ failure with non-whites is not just about voters’ economic circumstances.
