How accelerating change is deepening our political divisions

This column takes its name from its intention: it aims to explore the fault lines in American society and politics.

It is not designed to illuminate politics from the inside out, with tales of backroom maneuvering.

Instead its goal is to track American politics from the outside in. It aspires each week to chart how economic, demographic and cultural change is reconfiguring the American electoral landscape — and how the parties are responding to those changes in their agenda and strategy.

Years of unrelenting, even accelerating, change in our economy, culture and demography have carried the US into an era of polarized, fierce, and volatile politics. CONT.
