Honestly, I think I can make the claim that liberals have lucked out. When it first became apparent that Shrub would have to fill two SCOTUS vacancies and not one, I feared the ramming through of two Scalia-like Huns. I'm actually pleasantly surprised that didn't happen. I'm not entirely happy about Roberts, but I don't think he's the anti-Christ either. I'm reserving judgment on Meirs until I get more facts.
Don't take this to mean I'm not wary or fearful. I'm VERY concerned about what could happen to Roe vs. Wade and the separation of church and state. Those are my two biggest issues likely to be confronted by the court in the short- to medium-term.
What I am saying, though, is that it could have been a lot worse.
I am curious, however. It's obvious that both Roberts and Miers are Bush loyalists. (Miers seems to think GW is the most intelligent person she's ever met. Quite scary.) It will be interesting to see how their loyalty pans out once Bush is out of office.
