Forty years ago, viewers who wanted to watch the news could only choose from among the major broadcast networks, all of which presented the same news without any particular point of view. Today we have a much broader array of choices, including cable channels offering a partisan take. With partisan programs gaining in popularity, some argue that they are polarizing American politics, while others counter that only a tiny portion of the population watches such programs and that their viewers tend to already hold similar beliefs. In How Partisan Media Polarize America, Matthew Levendusky confirms - but also qualifies - both of these claims. Drawing on experiments and survey data, he shows that Americans who watch partisan programming do become more certain of their beliefs and less willing to weigh the merits of opposing views or to compromise. And while only a small segment of the American population watches partisan media programs, those who do tend to be more politically engaged, and their effects on national politics are therefore far-reaching.
In a time when politics seem doomed to partisan discord, How Partisan Media Polarize America offers a much-needed clarification of the role partisan media might play.

The Partisan Sort

by Matthew Levendusky

Published 1 December 2009
As Washington elites drifted toward ideological poles over the past few decades, did ordinary Americans follow their lead? In "The Partisan Sort", Matthew Levendusky reveals that we have responded to this trend - but not, for the most part, by becoming more extreme ourselves. While polarization has filtered down to a small minority of voters, it also has had the more significant effect of reconfiguring the way we sort ourselves into political parties. In a marked realignment since the 1970s - when partisan affiliation did not depend on ideology and both major parties had strong liberal and conservative factions - liberals today overwhelmingly identify with Democrats, as conservatives do with Republicans. This 'sorting', Levendusky contends, results directly from the increasingly polarized terms in which political leaders define their parties. Exploring its far-reaching implications for the American political landscape, he demonstrates that sorting makes voters more loyally partisan, allowing campaigns to focus more attention on mobilizing committed supporters. Ultimately, Levendusky concludes, this new link between party and ideology represents a sea change in American politics.
