[C]ontemporary research on race and state policy choice has tended to draw on classic arguments about group percentages without paying close attention to their conditional claims regarding group relations and positions. A key task, then, is to complement this approach with theories that are general in scope, focus explicitly on racial relations and positions, and conceptualize race as a constructed system of social classification.
