Are the newcomers really liberals? I know North Carolina and Georgia, when they had their booms, complained about all the liberal Northeasterners turning their states blue, but the reality in those states is that the newcomers are more conservative than the long-term residents. What really happens is that surging land values turned urban people liberal, just like they did generations ago to Northeasterners.
A lot that I have met came here from California. They are not conservatives. I’m sure a lot of others are good conservatives from other states but I haven’t met them.
