American Geographic and Electoral Mobility

Americans Move, But Will the Result Change?, Centre for Policy Studies, December 8, 2011. "The political effects of this shift are equally stark: in 2012, the Republicans will gain a net total of six electoral votes, if the states vote as they did in 2008. Of course it is unlikely that the state votes will remain unchanged, but the fact remains that President Obama will have to run harder in 2012 just to stay in place. The long-run trends of American geographical mobility are telling, slowly, against him."
