people move to exurbs, start attending megachurches, driving SUVs, and voting republican.
The same sort of rubbish was written of people moving to the suburbs in the '50's (I can even dig up a quote that looks rather like the one above). Guess what? It wasn't true then and isn't true now; very few people change their voting habits just because they've moved to a different sort of neighbourhood. If they vote Republican now, chances are that they were voting Republican back where they used to live.
Very true. Of course so many on this forum seem to think I'll randomly move to one and start voting Republican for some reason.
