Actually, the vast amount of new comers are as conservative, if not more so than those who are long time residents. Those fleeing these states are conservative, not liberals. Most liberals go to bigger states not small redneck states.
The developers sure seem to build little crammed-in communities for them to huddle in and pretend they never left California. Oversized houses with practically zero lot lines look more like the Liberal’s idea of “moving up”, to me.
