From a reader:

Jonah:
How do I even know that Miers is a reliable vote? The ‘reliable vote’
argument is not only, as you say, corrupt, but it may not even have the
virtue of being correct.
I get the impression that only reliable vote that many of those who are
supporting Miers care about is on abortion. I have many issues that
concern me as least as much or more than abortion. Where does Miers
stand on federalism issues? What are her views of the commerce clause?
How would she have voted on Kelo? Campaign finance reform? Has
she even thought about any of this?
I’m not likely to find out. She is a cipher and is likely to remain a
cipher throughout the confirmation process. George Bush has asked me to
trust him that she will decide these issues in a way that will make me
happy.
I don’t trust that he would decide these issues in a way that would make
me happy.
