Controlling campaign coverage

Thanks for the article "TV as Gatekeeper," March 12. I have often wondered who decides which presidential campaigns are covered and which are not.

My wonder has increased recently as I have seen polls which show a plurality of voters wishing there were other candidates in the presidential race. I am surprised that the campaign of Andre Marrou, of the Libertarian Party, is not getting more coverage. It seems that a presidential campaign run by America's third largest party would be of interest to voters. John Kell, Blacksburg, Va.
