W ith the finish line in sight for the presidential campaign of 2016, we decided to devote our pages to essays that examine and challenge the way we think about politics, democracy, and the American electorate. Why do voters make the choices that they do? How could political scientists have failed to foresee this year’s tectonic political shifts? And what aftershocks can we expect in the wake of Donald Trump? We tackle these and other questions in this special issue of The Chronicle Review.
