American Government: Constitutional Democracy Under Pressure highlights the dangerous tension between our constitutional principles and institutions and the populist heat that sometimes roils our national politics, including at the current political moment. Our constitutional democracy has been under pressure for some time, but few would deny that fears for its fate have deepened in just the past few years. We assume that our political institutions will limit and contain contemporary populism, just as the Founders intended and as they have in the past, but will they? An increasingly polarized electorate, urging their representatives to fight and never to compromise, may be stressing Constitutional limits.
