ED MORRISSEY: Christie vetoes gun-control legislation he demanded. “Perhaps Christie has figured out that his original position was nonsense. The Barrett is no more dangerous to public safety than any other firearm; the danger is in the person who holds it and their intent in using it, as is true for every other kind of weapon one can imagine. Or maybe Christie has just figured out that he wouldn’t have a prayer of winning the 2016 GOP presidential nomination with his signature on a gun ban.”
