This shouldn't surprise anyone: In SustainLane's ranking of the greenest cities in 2008, cities that were green leaned Democratic, while voters in cities that were not so environmentally friendly tended to vote Republican. Same goes for the city's leadership: You'll notice on this graphic that all of the top cities have Democratic mayors (or, in New York's case, an independent). There's also an economic divide; many of the greenest cities were also the most expensive to live in and had higher incomes, while the bottom of the list had cheap housing and poorer citizens. Here are the top and bottom 10:
