I would prefer Scalia be elevated, and then Scalia be replaced by a staunch conservative. Following Robert's jioning the court, the overall "balance" will probably be only more slightly conservative than it had been, but that would be a win and the Dims would be hard presses to prevent it. I'm still concerned about Bush appointing his clearly liberal buddy, Gonzales. That could be coming, and would net out to a more than slight idiological shift away from conservatism, which would be a disaster.
We would have won only with a Scalia for CJ and a replacement of Stevens (or Souter, or Ginsburg). Roberts is still a "?" (surely he doesn't look like to Rehnquist) and the Supreme Court remains anti-life and anti-business, among many other issues.
