The senator's accusations that Elizabeth Warren misrepresented herself are hypocritical.
It's not the Supreme Court, stupid. Scott Brown's first choice of Antonin Scalia as his favorite justice during last night's Massachusetts Senate debate evoked boos from partisans in the audience and delighted progressives, who hope it will cost him the election. But I doubt it dismayed the small number of undecided voters to whom Brown is appealing. I doubt Scalia is their favorite bogeyman, and I bet their votes in the Senate race will not be affected by concerns about the Court.
Will they be persuaded by Brown's repeated (unsubstantiated) accusations that Elizabeth Warren claimed Native American heritage to gain professional advantage? Polls indicate that most voters are unmoved by the controversy, which David Gregory opened with and lingered on last night. But most voters aren't undecided. If the undecided are relatively unengaged and uninformed politically, they may be a lot more intrigued by water cooler speculation about Warren's Native American bonafides than by disputed analyses of Scott Brown's record or the ideology of Supreme Court justices. Or so Scott Brown must hope. His attacks on Warren's character, based on questions about her heritage, are unrelenting.
