"Each administration’s junior staffers help to define 

their era’s brand of D.C. 'cool', in part based on where

 they live. In the Clinton, Bush and Obama years, 

young staffers generally settled in Washington’s central 

neighborhoods, but President Trump’s millennial aides 

have tended toward the city’s margins." ('City's margins'

 is a polite way of saying 'lunatic fringe'.)
