In this week's New Yorker, George Packer writes about Michael Bloomberg who, as the fourth richest businessman in the country, decided to get into politics.

...But unlike the financial titans of the late nineteenth century, who made it a business practice to buy mayors (and governors and legislators), Bloomberg instead bought the mayoralty, spending almost a hundred and sixty million dollars of his own money on his two winning campaigns. Then, unlike the robber barons, who corrupted public officeholders to serve private or party interests, the Bloomberg administration has generally offered a model of nonpartisan good government...

They say we get the politicians we deserve but New York seems to have lucked out. And, as Packer notes, despite his money, there are lots of reasons why Bloomberg would have trouble as a presidential candidate. An interesting possibility, nonetheless.
