@Degsme and Xando...

How are migration patterns indicative of changing political attitudes? People abandoning the blue states for red? People abandoning red counties for blue ones? How does that change anything in the aggregate (except for short term changes in the number of people represented by a political EC vote or congressional district)?

If people abandon a blue state for a red one, do they stop paying ACLU dues and join the NRA? As migration within a red state moves people from the rural counties to the blue cities, do they stop watching Nascar and become soccer fans? Wouldn't both trends tend to create more purple than anything?

What am I missing here?

(Damn, I hate these ludicrous red/blue labels. I'll give my next paycheck to the network that switches the colors on their next electoral map.)
