This study relies on online surveys of politically interested web users during the 1996, 2000, and 2004 presidential elections to examine the degree to which people judge online information as credible and to compare how credibility has shifted in the past decade. Whereas credibility scores jumped in 2000, they declined in 2004. Online issue sources were judged the most credible and online broadcast TV news sources the least credible. Whereas respondents perceived few differences between online and traditionally delivered sources in the 2000 campaign, greater differences emerged in the 2004 campaign.
