Cool map.
On a semi-related but slightly off-topic note, Vermont is the state that most perplexes me. People can give me the "yada-yada" all day long about how the GOP has gone crazy and used to be more moderate or how the hippies and MA/CT/NY liberals moved in over the years, but it doesn't add up that between the 1970s (generously early) it went from being a very Republican state to being one of the bluest today. For YEARS, they elected fiscally conservative politicians, a few of which were quite socially conservative, too. That state's politics have had some of the most amazing shifts ever.
Less than half the population of Vermont was born there, and 90% of the newcomers are the sandals and Subarus crowd.
That first stat is amazing. I doubt even California (or any other state for that matter) matches.
