To the editor: The mayoral election is coming up, and I have two choices: I can vote for Chris Giunchigliani, an avowed pro-unionist who will back all unions as they continue — with their wage and benefit demands — to drag our economy into the toilet. Besides having that pro-union baggage hanging over her head, she has pundit Jon Ralston saying that she is a “cutthroat, often polarizing pol whose career has been characterized by hard work and extensive knowledge undermined by unnecessary nastiness and consensus un-building.”
