The Bush administration loves it, but many Justice Dept. officials think it’s illegal…Now, it’s the Supreme Court’s turn to weigh in on Boss DeLay’s gerrymandering plan in Texas. “Two years ago, justices split 5-4, in a narrow opening for challenges claiming party politics overly influenced election maps. Justice Anthony M. Kennedy was the key swing voter in that case, and on Wednesday expressed concerns about at least part of the Texas map.” (Rehnquist and O’Connor sided against the map challenge then, so a switch by Roberts or Alito will only mean a larger majority against the DeLay redistricting, should the same votes hold.) Update: Justice Ginsburg finds the subject exhausting, and Dahlia Lithwick reports in.
