Campaign finance laws that restrict who can contribute how much money, who can run political ads, etc., are all restrictions on political challengers who have to buy their own publicity.
If truth-in-packaging laws applied to Congress, a campaign finance law would have to be labeled an "Incumbents Protection Act."
The very high rate of incumbent re-elections, even while polls show the public disgusted with Congress in general, shows how well incumbents are protected.
The media are accessories to this scam. So long as the information and opinions that reach the public are selected by mainstream media people, whom polls show to be overwhelmingly on the left, the left's view of the world prevails.
Hence the great alarm in the media, and in equally one-sided academia, over the emergence of conservative talk radio programs and the Fox News Channel on television.
No longer can the three big broadcast television networks determine what the public will and will not see, nor two or three leading newspapers determine what is and is not news. Nobody wants to give up that kind of power.
When businesses that are demonized in the mainstream media, and in academia, can buy ads to present their side of the story, that is regarded in both the media and academia as distortion. At the very least, it can cost the left their self-awarded halo.
It is fascinating to see how some people -- in both politics and the media -- can depict their own narrow self-interest as a holy crusade for the greater good of society. The ability of the human mind to rationalize is one of the wonders of the world.
