"If you repeat a lie often enough, it becomes the truth. But the most brilliant propagandist technique will yield no success unless one fundamental principle is borne in mind constantly and with unflagging attention. It must confine itself to a few points and repeat them over and over. Here, as so often in this world, persistence is the first and most important requirement for success".

A caveat to keep in mind as election year approachs and candidates will be bombarding voters with simplistic slogans like: "999 is the solution" or "less taxes, more jobs", or "Fighting for Peace".
