Media whores is a term used in the early 60's during campaigns and refered to publishers and editors of newspapers that would not cover a candidate without an ad buy. The buy was refered to as a "little kiss". The more money a candidate had the more of a story they would get from the "media whores". If a campaign made an ad buy and counted on a good story but were then disappointed they would "kiss off" the buy with a cancelation.
There are over 200 presidential candidates in 2008 yet you only hear of 17 and that is the results of the entire media being media whores. Media whores will write no news stories to whore up to wealthy candidates, hence Edwards hair cut, Obama Clinton Spat, and Hillarys clevage, and Hillary walking down the street in Clear Lake, Iowa got ink.
