From Andrew Sullivan

A fascinating graphic of how hermetically sealed we are becoming one from another. We don't even read the same books any more, depending on our blue-red identity. I agree ... that there's nothing wrong with a divided country. It can be fun! But a divided country where both sides don't even talk to one another? That's a little more worrying.
