Bill Thompson Files to Run for Mayor

There was already a "New Yorkers for Bill Thompson" website urging us to support his mayoral bid, and he's been dropping hints and -- most significantly -- standing up to Bloomberg, but today comptroller William C. Thompson put in his papers with the Campaign Finance Board and made it official. The Times says he'll report about $5 million in contributions and get another $1.6 million in matching funds, which puts him in a league with the front-runner, Congressman Anthony Weiner. (Councilmember Tony Avella is running too, and has about a quarter million, some of which he should devote to his campaign website.)
