From an outdoor smoking ban to required postings of calorie counts, Seattle has implemented just about every public-health policy that Bloomberg has dreamed up. Albany is a close runner up: the capital of New York State also has pursued all four of Bloomberg’s successful public health crusades, but has done so at a slightly slower pace than Seattle.

Is a soda ban in Seattle imminent? While the city has proved amenable to some public health ordinances, it has proved resistant to others.

In 2011, Washington State voted down a soda tax that had been approved by the legislature. Back in 2008, when bans on plastic bags were just coming into vogue, the Seattle City Council approved a 20-cent tax on the disposable bags. Seattleites were none too pleased: One survey found 63 percent of the city’s residents opposed the tax, which was later overturned by a voter referendum.
