Any Federal Court challenges (and they are to be expected) will be uphill attempts to undo the process which has to proceed by mid-January 2004--the deadline for filing for the Texas primaries. This puts the courts under a lot of strain--having to decide to "cancel an election" after the DOJ has carried out its Statuatory function in certifying the new boundries.
I never understood why Rick Perry (Tx. Gov.) only moved the Primaries back one week--to mid-March from early March. I knew that even one week pushed Texas out of the "Super Tuesday" process which will likely cement the Democratic nominee for President. That's a good thing. Campaigning and advertising in Texas becomes much, much less important now.
But if Perry wanted 2004 to have the new Congressional Delegation, why not delay things for 3-4 months, still plenty of time to run a primary and an election. Now it seems that Perry is dumb like a fox, he delayed for a week to acknowledge that DOJ needs sixty-days (no more) to pre-approve, then the Federal Courts have a few weeks to decide to "cancel/delay the election" or else to let people file for the new Primary districts and then possibly change things after the campaigning truly starts.
