The people moving from a blue state to a red state because they feel the people running the blue state screwed up are going to keep voting blue? I've never understood that logic.
Presumably there are people in the world with a finer-grained view of things than "blue" and "red", such as centrists, people sympathetic to progressive social views but not a fan of progressive economic views, people hurt by Prop 13 in particular, etc.
(It is certainly possible that such people are working to improve their home state and the only people actually moving have a dualistic view of politics, though.)
The politicians who had progressive social views but who were not in favor of progressive economics are long gone from the political scene. There are only red and blue left. Witness the demise of the Blue dog Democrats with one vilified exception.
