Exposing the Anti-War Movement: MoveOn.org (Your Don't Know Jack!)
Bill Moyers, a LBJ flunky media aide and a man who was never a reporter before he wrapped his mouth around a government teat at PBS, produced the infamous ad attacking a true American, Barry Goldwater.
Here is a WND.com description of the ad. "It opened with a little girl counting the petals on a daisy on a beautiful day. It ended with a nuclear mushroom cloud and the ominous warning that this was the inevitable result of a Goldwater victory."
The RNC protested and to the best of my recollection the Democrat Party pulled the ad after just one showing nationally -- that is, one paid showing.
It was shown only once so how did so many people see it? It became a "news" item. The evening TV "news" showed it free for days (if not weeks!) while they "reported" on the controversy.
