Michael Bloomberg likes to portray himself as a moderate, sensible man whose supposed reasonableness contrasts with the partisan sniping that defines most American politics. By putting feelers out for an independent presidential run, however, Bloomberg shows how unreasonable a man he actually is. No reasonable person wants Donald Trump befouling the White House, but if Bloomberg throws his hat into the ring, the possibility of a Trump win rises dramatically. The blunt fact of the matter is that Bloomberg isn't going to win.
