The Big Lie Ploy

The "Big Lie" ploy works because it is so blatant, outrageous, in-your-face that it is assumed to be true. It works too because in politics that at least 30% of one side of an ideology will believe anything said or published by their side. It works too because propagandists ardently defend it to the extent that others automatically assume that it has to be "true". Repetition of it over and over again in the face of debunking it makes it "true".
An example of the "Big Lie" is in McCain's claims about Barak Obama's tax plan, stating that Obama will raise the people's taxes when in truth 80 to 95 percent of working class people will get tax breaks.
Another example of McCain's "Big Lie" ploy is in stating that his running mate Sarah Palin, while governor, refused "ear-marks" when in fact received money for questionable projects from the Fed. McCain insisted, when confronted on "The View" about it, that Palin did eliminate ear-marks while Governor of Alaska. It will be interesting to see for how long they try to keep the "Lie" going.
