With the housing bubble burst there aren't many people moving anywhere right now.

I never noticed it before and I don't notice it now. People move for a lot of reasons -- jobs, retirement, family, and others. I think your television program was desperate for a story and thought that maybe perhaps this might possibly be one if it were true.

I exempt certain retirement communities in Florida, but even in those (and they're rare enough to make the news HERE) members of all the political parties live.

"Polarization," excepting the fringes on both sides, seems to be more of a media event than actuality.
