the reaspn why VRA districts are important in Texas is because of polarized voting habits. According to DRA, the precincts where whites make up a majority gave McCain 68 percent of the vote. The precincts where whites don't gave Obama 63 percent.
And, if Hispanics in places like Collins County started voting like their White Neighbors, and Whites in poorer areas started voting more like their Hispanic peers, the result would less "racial polarization" in voting, but, a larger McCain majorities in "White" precincts, and a higher Obama majorities in non-White majorites.
What if whites started voting like their Hispanic neighbors?
