Absolutely fascinating study though. Maybe the first time (at least I've seen) that we've identified the political leanings of the American electorate. Americans run the gamut on cultural issues, but we are fundamentally a centrist/center-left country in a global sense. We have a welfare state to a certain degree that conservatives and liberals alike support, we accept government's role in providing social services and economic assistance during recessions. I'd love to see similar charts for other elections, and perhaps other nations too. I assume that electorates in western Europe are for the most part further left than ours, whereas maybe eastern European and Middle Eastern electorates are more to the right.
We tend to follow the Anglo-Saxon version of the European social model. Some states, however, follow the Nordic or Continental model.
