I don't know, he's a comedian, he does comedy things. He's got 22 minutes to make people laugh. 22 minutes vs the 24 hours of fox/cnn/msnbc/etc. The writers on the show usually have a list of news stories, think about what is funny about them, then write a joke and hopefully they can find some old footage they can poke fun at too. I don't think they are even thinking about equal time, because that takes away from the funny. But he is known to have deep discussions with authors, politicians, and pundits which are available on comedy central's websites for interviews that run longer than the show. The ones with Bill O'Reilly are particularly good http://thedailyshow.cc.com/guests/bill-oreilly he's done these with Ron Paul and other Republican and Libertarians too.
