Two Texas cities represent the divide between those who vote and those who could, but often don't

Two neighboring Texas cities illustrate the divide in American politics between the diverse, potential electorate in the country and the actual electorate, which is heavily white and wealthier. For a long time, the presumption has been that closing that gap between places like Lewisville and Flower Mound north of Dallas would help Democrats and hurt Republicans by getting more people to vote and having the electorate better represent the actual population. That's because a larger electorate would mean more minorities voting, and those groups historically lean Democratic. But this presidential election has flipped the script.
