Now all you have to do is tell me why they are the dumbest posts in your opinion, which should be easy for a smart fellow like yourself ...
It has been explained to you by multiple posters already. But since you asked so politely and in such a complimentary manner, here’s just the two most obvious reasons that spring to mind:
The idea that “the people” always see through propaganda and vote for the “right person” is just . How did the 1932 elections in Germany go, under your hypothesis?
But god forbid I violate Godwin’s (now suspended) Law... instead, let’s assume for a moment that you are correct and that “the people” always make the correct decision...
3 million more people voted for Hillary Clinton than for Donald Trump.
Secondly, your assertion that Brexit is an example of a FAILURE of propaganda is ridiculous to the point of self parody. As has been mentioned previously it is precisely BECAUSE of propaganda (both during the campaign and arising from a media environment that had existed for the previous several decades) that Leave was able to win.
