sorta like the media does. When there is a quorum, usually more than two people on a subject they want to high light and one holds up a sign that says so and so is failing...it gets reported and repeated.
Yesterday NBC reported the two rallies in FL; Obama and Palin. They showed the lines in Daytona Beach where it was highlighted that "...some 2500..." tickets were handed out to eager participants. Then they went to The Villages and panned up Canal Street talked about the retirement area Palin was going to have a rally in....however there was no pictures of the lines or the 16,000 tickets handed out. I wouldn't have expected anything different from any of the network news.
They look through a straw at the side of an elephant and see gray. They then proceed to report the whole world is now gray. All the loyal parrots proceed to pass along the world is gray.
About the only news of relevance from the networks is pending bad weather, and they make a scary entertainment production out of that....so one is better off looking out the window.
