The close results of recent presidential elections reflect the emergence of a highly divided and partisan electorate

摘要

Over the past four decades, the American electorate has changed dramatically. As a result of these changes, Alan Abramowitz argues that we have entered a new and fundamentally different era of competition in presidential elections. The key features of this new era are a close balance of support between the two major parties, a strongly partisan electorate, and a high degree of stability in voter preferences and in the outcomes of elections at the national and state levels. Just as is important, is the growing Democratic advantage in both the national popular vote and the Electoral College due to changing demographics.
