This is the most telling paragraph:
"Just pause for a moment and think about the town or city you call home. How many of your neighbors voted the same way you did in the last presidential election cycle? Probably most of them. And if they didn’t, research
indicates you may be considering relocating sometime soon.
Just 40 years ago, most districts in the US
were swing districts. Today, less than half of them are. And this is unlikely to change anytime soon, as more and more people
move to neighborhoods where they likely won’t encounter anyone who holds an opposing political view.
So, what happened over the last four decades? Journalist Bill Bishop explains we’ve been self-sorting ourselves since the 1970s, when geographic inequality in education grew. That meant Americans with college degrees began clustering in big cities, while less-educated people remained in more rural areas. And jobs migrated accordingly, with technology and production following the new city dwellers.
This clustering was followed by the rise of partisan media, social media networks and a market that was built quite literally on catering to those divisions. In other words, entire identities — defined
by diet,
media patterns and
size of home — have been created around party affiliation. And, as sociological research
explains, place, and even consumption habits, have become a way of creating identity and broadcasting it to the world — or, at least, our closest neighbor."
