As a one-man economic stimulus plan, Mayor Bloomberg is doing his part.  His campaign has spent about $7.5 million of personal funds so far, according to this Times article.

Mr. Bloomberg, a billionaire, has now spent more than the city’s campaign finance laws allow Mr. Thompson — or any other challenger accepting public financing — to use in the race from now until the September primaries.

Mr. Bloomberg is not accepting public financing, and therefore faces no spending limit.

The spending gulf between the mayor and Mr. Thompson is prompting an outcry from several academics and good-government groups.
