Donald Trump and Michael Bloomberg are both wealthy New Yorkers with a penchant for putting their names on tall skyscrapers.

They like to project an image of corporate success, to bluster about their professional conquests – imagined and real – and share an ugly habit for saying distasteful things about women and ethnic minorities in the presence of hot microphones.

Bloomberg’s rivals, from Bernie Sanders to Joe Biden, have been quick to draw the parallels in their respective campaign spots, while the former Big Apple mayor’s debut on the debate stage in Las Vegas this week saw him mauled by Elizabeth Warren along the same lines.
