Americans are too worried and, at the same time not, worried enough about political polarization. Ideological rivalry is a good thing, not a bad thing: It's the reason for democracy, not a drawback of democracy.

It documents the growing ideological distance between Democrats and Republicans, not just in Washington but in the country at large. The information is fascinating and disturbing — but it doesn't do justice to the pathology it's describing. You could put it this way: The quantity of polarization isn't the main thing; what counts is the quality of polarization.
