How much does consuming news with a strong political slant influence Americans’ votes in presidential elections? And how strongly do people prefer news sources that are slanted towards their own political preferences? This research provides evidence on the persuasive effects of slanted news and viewers’ tastes for like-minded news by analyzing data on the three big US cable news channels: CNN, Fox News, and MSNBC. The results indicate that these news sources – and Fox News in particular – have the potential for large effects on the outcomes of elections.
