Sunday Streets, like any gathering, is a target audience for politicians.
David Chiu campaign stops by the Lindy hop dancers. Constituents are where you find them.
TV station gets people to dance with their logo, and sing their little station ID song. Embarrassing, brainless monkeys shaking it for corporate overlords.
Despite the inevitable politicization and commercialization, Sunday Streets is a wonderful event, where one can witness human happiness over and over.
