Redistricting has been a contentious issue in Texas for the last few years.
Here's a look at the history. In 2001, federal courts drew up redistricting lines after the Texas Legislature failed to agree on a plan during its session. Republicans tried to re-draw lines when they took control of the state legislature after the 2002 elections. Fights over the plans led to Democrats leaving the state twice in 2003.
In October of that year, the legislature passed a new redistricting map. Democrats though continued to challenge the new lines saying the map disenfranchised minority and rural voters. In December of 2003, the justice department gave the new lines the green light, ruling the map did not violate the voting rights act.
Finally in January of 2004, a three judge federal panel approved the new redistricting map.
