The 2008 presidential campaign, as reflected in candidates' television spots, has been one of the most negative campaigns in history. A University of Missouri professor analyzed this year's candidates' television spots, including last night's 30-minute ad by Sen.

William Benoit, professor of communication in the College of Arts and Science, found that in television spots from 1952-2004, candidates averaged 40 percent attacks in their ad statements. In this year's race, the statements in Obama's ads were 68 percent negative compared to 62 percent for Sen. John McCain.
