Smart people watch the 'Daily Show'?

from IMDB:

Concerns that people who receive their political information from late-night comedy shows may not be adequately familiar with the issues in order to vote knowledgeably appeared to be laid to rest Monday by a study conducted by the University of Pennsylvania's National Annenberg Election Survey. In a poll conducted between July 15 and Sept. 19, nearly 20,000 young adults were asked six questions about the presidential candidates' stands on various issues. Those who watched no late-night comedy shows answered 2.62 questions correctly. David Letterman's viewers answered 2.91; Jay Leno,'s 2.95; and Jon Stewart's (The Daily Show) 3.59. The results for Stewart appeared particularly striking to the pollsters, who noted that his viewers "have higher campaign knowledge than national news viewers and newspaper readers."
