Is "wait till we hear what she has to say at the hearings" a way of saying "maybe something will turn up" that doesn't sound quite that helpless ? Like when a woman says "I have x years invested in this relationship" she is saying "Maybe he'll change" in a way that doesn't sound quite that helpless.
If you can come up with no credible explanation for why she deserves to be on the Supreme Court at this point, why was she chosen ? Does a boss interview everyone who sends him a resume ?
He would probably interview someone whom he knew for 14 years as well as Bush knows Miers, especially if he thought she was qualified for the job.
