San Francisco Mayor Gavin Newsom, a Democrat best-known for directing his city to recognize same-sex marriage in 2004, announced today that he's running for governor of California. But there was no rally or speech. He spread the word on Twitter and Facebook. "It's official- running for Gov of CA. Wanted you to be the first to know," he told his Twitter followers.

On the one hand, I suppose this keeps with Newsom's reputation as a young, with-it politician. On the other hand, I cringe at the idea that he might say, upon victory or defeat in 2010, "We launched this campaign last year with a single Tweet."
