Firmness of principle is not the same thing as mindless repetition.
Firmness of principle implies that you're acting on a principle, and nominating Miers was not an act of principle. Sticking with a bad choice only makes you look foolish to the folks who desperately want you to make a good choice.
We were told in the early days that Bush was a good poker player, and I forgave a lot of poor communication and poor leadership on the grounds that he was playing close to the chest. The last couple of months have destroyed that illusion. He doesn't know when to hold 'em and when to fold 'em. He finally tossed this pair of 4's down, but he (and we) have lost considerable ground while he held 'em.
