I think the "brains" of the left have come up with a model that's based on military planning. They've predefined a set of pre-planned action packages and, to go with them, predefined "trigger events." They watch the domestic news wires 24/7, and, when a potential "trigger event" occurs, they convene a conference call within a very short time frame and decide whether that event reaches the threshold for one of the action packages. If they decide it does -- and the White House may be involved in the decision -- the packaged plan is put into motion.
I think it's pretty well established that this is what happened in the Limbaugh/Fluke situation. The whole thing, including the calls by local "ordinary citizens" to local radio stations and their local advertisers, was set up in advance. They'd been waiting for Rush to say something that reached the threshold for some time -- years, I think -- and, when he did, their plan was put into action immediately.
Games and Theory earmarks are all over their every press release and every meme that gets pushed out to the sheeple.
That's absolutely how they do it.
