Even the conservatives don't like her:

The supreme court should be the place where the best judges in the land end up. The people who have the experience dealing with the issues on the ground, have heard many legal arguments in the past, and have proven themselves able to put their personal views aside to deal the with issues before them by consulting the constitution and the law, not the bible or by having a prayer session.
Judges toil for years to move up the ranks, and many good, solid, and proven judges exist in the top federal circuits who could graduate to the top level - the the experience and understanding required to go right to work without rocking the boat.
The senate judicial committee should have one look at this nomination and say "sorry, we want someone with a little experience to make up for that new chief justice who doesn't even know how to put robes on right yet". She may be smart and she may be loyal, but she also has no history and no way for anyone to "judge the judge". Roberts was just about a blank canvas, and Meirs is the total absence of even canvas, just an empty studio with "nothing to see here" on the door.
