The Supreme Court on Monday ruled against a challenge to Texas' redistricting methods in a case that could have dramatically tilted elections nationwide in favor of Republican candidates. In Evenwel v. Abbott, Sue Evenwel and Ed Pfenninger had sued the state of Texas over its 2010 redistricting map, contending that it diluted their votes—i.e., those of largely white, rural residents—by basing legislative districts on total population as opposed to eligible voters. Such a method of drawing districts, they argued, meant that urban areas with large numbers of illegal immigrants or felons would have more representation in the state legislature than rural areas with fewer people but a higher percentage of eligible voters/Mother Jones.
