Blue states seem to be losing residents. South Carolina's population increased 15% and we will likely pick up one new Republican seat in Congress since both legislative houses and the governor's mansion are controlled by the GOP. New York state, controlled mostly by Democrats, will lose 2 seats. Pennsylvania also loses one seat but they could still gain one Republican seat if the new Republican governor and legislature create a new majority Republican district in the Philadelphia suburbs.
These new census numbers will contribute to the titanic shift toward conservatism that started with the 2010 elections. If this trend continues I doubt Obama will win re-election and the Republican majority in the House will get even bigger.
