Texas underwent a second round of mid-decade redistricting as a result of the Supreme Court case League of United Latin American Citizens v. Perry. The court had ruled that District 23 violated the Voting Rights Act.[1] Due to this ruling, the 15th, 21st, 23rd, 25th, and 28th districts were redrawn after the primary election had occurred, voiding the results. These districts instead conducted special elections concurrent with the general elections.[2] This election marks the first time Democrats made a net gain of seats over Republicans since the 1992 elections.
