From 2000 to 2010, Texas’ population ballooned by 4.3 million people, giving the state four new congressional seats. Latinos and African Americans accounted for roughly 80 percent of that growth. But when Texas drew new political maps in 2011, it created four majority-white, safe Republican districts. The Supreme Court could rule next year on the constitutionality of this extreme gerrymandering, as well as two other voting rights issues that could shape the future of politics in Texas and across the country.
