I read somewhere in the numerous Miers threads, that Specter likes Alito.
That's nice. I think Specter's deep friendship with his political appearance and future outweighs that. He is more about "style" and less about substance.
He needs to be reminded about the last election cycle, who supported him (against a much stronger Republican rival, yet!) and why that "machine" can make him disappear into the cornice moldings of his cushy Senate office....
