Here's the abomination of a map:
In Texas any district that can be entirely contained in one county must be put into one county. only one district in a county can spill over into other counties, and it has to contain whole counties. For example in the 2002 redistricting my county qualified for 2.4 state representative districts. There were 2 districts entirely in my county and one that was split between my county and a few other whole counties to the north. It makes it pretty much impossible to have multiple districts stretching across the state. I am pretty certain the Illinois gerrymander would violate the Texas constitution if anyone tried to impose a similar system in Texas.
