Would John McCain offer a “no McCain-Feingold litmus test” pledge on Supreme Court appointments? I expressed doubt this morning. Well, not only did McCain defy my expectations, he did so a couple days before I expressed them. A kind colleague hereabouts has pointed out a Corner post from Monday that I missed, in which NRO’s Mark Hemingway reported that he got the Arizona senator on the record that “McCain-Feingold would not be a litmus test for the justices he appoints.”
