Waiting for the hearings is, IMHO, pointless. Miers will no doubt adopt the Ginsburg strategy, leaving many unanswered questions on her positions.
If she does that, she might just face some Republican opposition. She has to give us an idea who she would be on the bench, while not saying how she might rule on a specific case. If she pulls this off, I'd say President Bush put the wrong one in the CJ post.
I don't expect her to tell us how she would rule on a case before it comes to the Court
Though I do expect to see if she has a true understanding of the Constitution .. cases that have come before the Court and who exactly makes the laws .. ampong other things
