Counterpunch has the article Why Ridiculous Official Propaganda Still Works.
The primary aim of official propaganda is to generate an “official narrative” that can be mindlessly repeated by the ruling classes and those who support and identify with them. This official narrative does not have to make sense, or to stand up to any sort of serious scrutiny. Its factualness is not the point. The point is to draw a Maginot line, a defensive ideological boundary, between “the truth” as defined by the ruling classes and any other “truth” that contradicts their narrative.
Come to think of it, this technique is so powerful that both Elizabeth Warren and Bernie Sanders have fallen to this power. At least Bernie Sanders seems to still be figting it although he had completely succumbed during the general election. The evidence I see is the support Warren and Sanders gave to Clinton, even though they couldn’t possibly have believed the supportive things they said about Clinton. If you think they really believed what they said about Clinton, then everything Bernie Sanders said about Clinton in the primary season and everything that Warren had said and written about Clinton before her endorsement of Clinton were lies. If you know that one of the two sets narratives had to be lies, how do you know which one to believe? One way to figure it out is to look at which narrative comports with the facts about Clinton that you have learned over the years independently of what Sanders or Warren have said.
Two examples should suffice to give you the idea of what I mean. I don’t think there is any doubt that Bill Clinton pressed the case for bank deregulation and NAFTA against the will of the majority of the Democrats in Congress at the time. He enlisted Republican help to get these two things passed. These two things match what Warren and Sanders have been saying for years. These two things directly contradict what Warren and Sanders said about Clinton after Clinton became the official nominee.
