Joan Walsh kicks off the New Year with a revival of my favorite self-pitying talking point from the soy-’n’-socialism set: Liberals lose out in politics because they are too 1. nice; 2. honest; 3. pure; 4. loving; 5. decent. Yeah, tell it to Charlie Rangel and Barney Frank. Tell it to Bill Clinton. Tell it to the ghost of LBJ. Tell it to Joan Walsh, for that matter, editor of “petrified chimp” hit pieces. Too pure is not liberals’ problem; too squirelly is.
