The release of 2000 Census figures last December kicked off one of the fiercest political battles the nation faces: the redrawing of congressional districts based on population changes. The delicate job -- whether by state legislators or members of special commissions -- invariably is accompanied by intense pressure from partisan political interests whose power may shift along with the boundary lines. In addition to partisan considerations, state legislators may redraw boundaries to suit their own political ambitions. And ethnic and racial minorities may push for districts that will ensure them greater political power. Meanwhile, lawsuits from interest groups are likely to threaten virtually any new districts, especially ones where minority groups comprise the majority.
