Let's face it: This is less about Miers' "qualifications" than about the fact that we've been itching for a fight with the left.
After all, no one questions whether a lunatic like Souter is "qualified," do they? No, they don't. And Republicans *never* questioned the "qualifications" of a lunatic ACLU lawyer like Ginsberg. But they're sure raising a stink about it now.
What? Are progressive republicans concerned that Harriet might not find a justification for gay marriage in a penumbra emenating from the Equal Protection Clause?
It's not "progressive" Republicans making a stink about this, it's grassroots patriots wondering whose interests she will serve on the court and how well she will serve them.
