How politics makes us stupid - Vox: In the mid-20th century, the two major political parties were ideologically diverse. Democrats in the South were often more conservative than Republicans in the North. The strange jumble in political coalitions made disagreement easier. The other party wasn’t so threatening because it included lots of people you agreed with. Today, however, the parties have sorted by ideology, and now neither the House nor the Senate has any Democrats who are more conservative than any Republicans, or vice versa. This sorting has made the tribal pull of the two parties much more powerful because the other party now exists as a clear enemy.
