This document discusses trends in news media coverage of presidential elections and campaigns. It summarizes the views of scholars like Thomas Patterson and John Zaller on why election news coverage has shifted over time towards more "horse race" reporting, negative coverage, and trivial issues rather than substantive policy discussions. Zaller's view is that the goals and actions of journalists, voters, and candidates all interact to shape news coverage, rather than any one group being solely responsible. He argues that candidates' increasing efforts to tightly control their messages can help explain increases in negative press-initiated coverage as journalists push back against such control.
