While scanning the DK and SSP archives, I found a whopping 29 maps of Texas. Among them were plenty of gerrymanders for both parties, as well as racially-based and "court-drawn" maps. The prizes for most extreme gerrymanders go to Warning Crazy (36-0 GOP map), TXMichael and Andrew (possible 22-14 maps) and the most beautiful map being wwmiv's. Not seeing anything crazy enough, I went for broke, abandoning legal considerations to create as many winnable districts as possible. Thus, my only considerations were partisan performance, contiguity and +/- 1000 variation.
What I wound up with were 24 Obama districts, 23 of which were 53.8%+, thus at least D+0.9. I also have 51% and 46% Obama districts in rural east Texas plus Waco that I think both Max Sandlin and Jim Turner could win if they ran (they're still average Congressional age). So we could potentially dominate the delegation 25-11, though many seats are shaky. The 17 non-DFW/East TX districts are 55.5%+. This map is so scrambled that I won't bother relating seats to incumbents. I'll note that it is theoretically possible to make one more seat competitive in DFW by splitting Frisco, McKinney, Allen and the rest of Plano, but it would make six 53-54% seats into seven 50-51% seats. That doesn't seem like a good trade to me.
Also note: Dem average is of all (non-competitive) Prez and Gov races from 2002-2010. There is also a 19.8% Obama district, or R+33!
On to the maps!
