The fact is that the Dems don't like the idea of their 1990 Gerrymandering being reversed. IOW, these are the kind of people who hit a home run in the top of the inning, then declare the game over and insist that they won.
Btw, if the SC should rule the wrong way, and throw out this set of districts, how does that affect this year's election? I would think there might not be time to re-draw them for 2006. If the districts remain in place then that is good news but if they have to revert to the old map then that alone could cost the GOP a large portion of its already slim House majority.
