It is now becoming clear that Clinton’s ground game — the watchword for defenders of her alleged competence — was actually under-resourced and poorly executed. Like so much else in this election, her field strategy was hostage to the colossal arrogance and consequent incompetence of the liberal establishment.

At the heart of the failure was the notion of the “new emerging majority.” According to this argument — pushed by, among others, John Judis and Ruy Teixeira — women, Latinos, blacks, and skilled professionals who support the Democrats were becoming the demographic majority. Thus the traditional white working-class base of the Democratic Party could be sidelined.

Back in July Chuck Schumer summed it up: “For every blue-collar Democrat we lose in western Pennsylvania, we will pick up two moderate Republicans in the suburbs in Philadelphia, and you can repeat that in Ohio and Illinois and Wisconsin.”
