Perhaps Specter cares more about the Chairmanship than he does the shape of the judiciary???
An interesting point. Wouldn't put it past the shmuck to be so child-like. I find it difficult to trust him though when right after the elections, I mean right after, he came out and virtually said that there could be some problems with Bush's nominations. I mean, Bush campaigned hard for him, and this is how he repays him.
I find it hard to trust a man who would so quickly stab the back of one of his allies. Along those lines, if I were Rick Santorum, I wouldn't really be counting on Arlen's support when it comes time for reelection, if even the slightest, scandalous news is attached to me in the intervening time.
