This is unquestionably the best campaign ad of the year.

San Francisco will hold a mayoral election on Nov. 8, with interim Mayor Ed Lee seeking a full term after being appointed to his post when Gavin Newsom, his predecessor, was elected lieutenant governor last year. MC Hammer, San Francisco Giants closer Brian Wilson,, and Twitter co-founder Biz Stone all evidently want him to win.

Lee is the front-runner against more than 10 opponents.

The YouTube video was produced for $18,000 by Portal A Interactive, a media firm comprised of three 27-year-olds based in San Francisco and L.A., at the behest of San Franciscans for Jobs and Good Government, a pro-Lee group backed by Silicon Valley angel investor Ron Conway. The guy who raps the verses is Ashkon, a San-Francisco-based rapper/entertainer/Giants fan who recorded this video with Portal A last year during the Giants' World Series run.

Conway is friends with MC Hammer, according to a spokesman for the group, and reached out to all the celebrities himself. He announced the video on Tuesday in a Huffington Post entry.
