Are We Divided? Or are the Elites Divided?

My headline above sums up an old political science argument -- are political divisions the stuff of real people, or just the stuff of political elites?  This brief but excellent The Atlantic column gets into it.  Ultimately he blames the elites, the chattering class, not regular folks, for the festering political divide.  And the data kinda support this, that most of the partisan divide can be found among political elites, chatterers, and news junkies -- not real live regular people.
