I dispute this: "Since newspapers do not have the same space and time constraints as television or radio, newspapers are able to provide readers with more information on both sides of an issue." I could read the newspaper three times and work the crossword puzzle twice in the three hours I spend listening to Rush.
In contrast, most radio talk show allow for listener calls. Radio commentators have to defend their opinions on the fly. They hear objections they have never contemplated and they are scolded by experts they never contacted. Liberals do poorly in verbal defense as their opinions are fluffy feelings - - facts are hard to fudge.
