From Ryan Sager. (Hat tip: chart porn)
I love the presentation of these data. The only thing that would make it better is to have an animation of how these data move over time. I suspect that the order of the states has stayed fairly constant over time but that the points in each state continue to move further to the right. How long before most of the X's are to the right of the 50% line? My guess is 15 years.
