GOP gubernatorial candidates Paul Mango and Scott Wagner are hardly the first to violate Ronald Regan 11th Commandment, “thou shalt not criticize thy fellow Republican,” but the viciousness of their television attack ads is remarkable. It’s a sign, also, of just how mean and dumb the GOP has become as its candidates willfully trash each other for being insufficiently “conservative” (a word that’s lost all meaning in the age of Donald Trump).
