The nomination of Judge John Roberts is driving some Democrats to distraction because he is probably ultimately un-Borkable. As my colleague Gene Healy wrote, Roberts’ selling points include “[g]reat grades, stellar resume, nice posture, nice smile, [and] no doubt a firm handshake. But where he stands on anything is anyone’s guess. What we’ve got here is a guy who, apparently, was genetically engineered and grown in a vat for the sole purpose of getting past the Senate Judiciary Committee.”
