I calculated this out. In the four uber-liberal boroughs of NYC (not Staten Island), DC, Cook County (Chicago), Los Angeles County and the four largest counties of the San Francisco Bay Area, Clinton put up a victory margin well over 6 million (so far; still counting in California).
Take out those 11 counties - home to most of the elites and crazies on the left - and Trump would be leading the popular vote quite handily, probably by more than 5 percentage points.
Surely Boston deserves to be included, which would run the number to an even 12.
