I think we are underestimating the impact of environmental issues on the ski resorts. There are probably more single-issue climate change voters there than anywhere else in the country. These people go into the voting booth thinking about snow, either because their livelihood depends on it (resort owners and employees) or because they don't have any other worries in life (wealthy patrons/retirees). A similar trend might be expected to develop over time on the Florida beaches. In Europe, where global warming and the environment in general is much less of a left-right issue, these people would be conservatives.
indeed, though theme parks trend dem for other reasons mentioned above.
