Why couldn’t he look more like Bork?

Nothing annoys the left more than a conservative it cannot easily demonize (the left is still compensating for its failure to demonize President Bush, treating him instead as just a fool, until it was too late). Consider E.J. Dionne annoyed. Nobody’s fool, Dionne has figured out that, despite his engaging personality, John Roberts is a conservative. What he hasn’t figured out is an argument to support his premise that, notwithstanding the past few election results, a conservative does not “belong[] on a closely divided court.”
UPDATE: Pia Catton in the New York Sun summarizes in straightforward terms part of the problem Roberts poses for the Dems.
