Nothing stopping Doggett from moving across town and running in the 25th. I think he would have a significant chance of winning, particularly in a light-turnout primary on March 9.
I don't think the GOP has shoved in enough judges to get this map to pass.
Tom DeLay, in his infinite arrogance, probably thinks it will survive court challange...but I see both Equal Protection and Voting Rights issues galore.
And Dewhurst has said if this doesn't pass muster then that is it until 2011.
Hopefully it is SO evil it will get bounced.
