By my calculation, we need THREE conservatives selected to replace O'conner, Renquist, and TBD (Stevens, Ginsberg). Conservatives should settle for nothing less. Why should we?
I think 2 very strong Conservatives would swing the court towards the limited duties defined in the Constitution though I certainly would like 3. I believe a moderate conservative (if there is such an animal) nominated by Bush to the Court of Scalia or Thomas with two other strong conservatives appointed would be very much inclined to lean toward the Constitution for decisions or at least to the right.
