ALL THE NEWS YOU WANT TO HEAR THE IMPACT OF PARTISAN NEWS EXPOSURE ON POLITICAL PARTICIPATION

In a news media environment characterized by abundant choice, it is becoming increasingly easy for Americans to choose news sources slanted toward their own political views rather than sources providing more diverse perspectives. This development poses a challenge to ideals of deliberative democracy if people who consume politically like-minded news disproportionately populate the electoral process, while those presumably reaping the benefits of exposure to more diverse views in the news (e.g., more informed, tolerant attitudes) withdraw from politics. Using panel data collected during the 2008 presidential campaign, this study investigates the proposition that exposure to news slanted toward one's own partisan views increases political participation, while exposure to news with the opposite partisan slant depresses participation. The results suggest that, while exposure to partisan news does not alter the strongly habitual decision to turn out, the hypothesized energizing and enervating effects of exposure do appear for other behavior during the campaign; the partisan hue of the news sources citizens choose to consume affects both when voters decide and their levels of participation over time.
