At a moment when everyone from the vacuous Times columnist Tom Friedman to most voters watching Washington antics wish there was another way forward, maybe Bloomberg thinks he can make a go at being an attractive alternative who has not completely denied realities like climate change and racialized urban poverty, realities that neither party dares address at all.
Bloomberg took a brief run at a third party bid in 2008 -- maybe this time around the country is ready for a 69 year old billionaire? (After all, we just tried a fresh youthful face and got what appears a damn slow learning curve opposed by a bunch of lunatics.) And the Times article linked above indicates that, at least in that initiative, Bloomberg has fellow billionaire George Soros on the program with him.
Somehow, at a time when the richest one percent of earners grab nearly 25 percent of the country's income, it seems natural that rich men should think they could buy their way to saner policies. It's worked fairly well for New York City, or at least for Manhattan and parts of Brooklyn. That is, if you set aside the damage to democratic (small "d") principles that comes with changing the rules of the game for an incumbent mayor (term limits were overturned to give Bloomberg a third term) and with the inhibition of communities from growing their own new leaders. But hey -- the guys with money don't have to do all that messy politicking. ...
I don't think this will actually go anywhere; the inertia in the system is likely to keep working. Maybe 2016? Bloomberg would only be 74. Anyway I hope Bloomberg keeps spreading his wealth around -- if we aren't allowed to tax the rich as the price of their citizenship, we need their vanity campaigns.
UPDATE: The Times has followed up by checking out response to Bloomberg's initiative for Black and Brown male youth employment in some of the neighborhoods.
