I certainly agree with Moore's point of view more often than I do Limbaugh's but, asside from my own views, I think parallels can be drawn between them.

• They both make their living in the entertainment industry.
  
• They both bend the truth and use “over the top” humor to ridicule the stupid actions and pronouncements of those they oppose.
  
• They both have loyal followings of people for whom humorous carping is an engaging substitute for political action.
  
• I assume they've both become wealthy by entertaining their loyal fans.

Fortunately for them both, there is never any shortage of stupid actions and pronouncements to use as fuel. If one is genuinely interested in information on current affairs, though, the entertainment industry may not be the most reliable source. Reliance on these people is one of the things that keeps the U.S. from having an informed electorate.
