why we all failed to predict the triumph of the TRUMP counter reaction to Obama's moves towards greater tolerance
I won't go as far as to call it a law of political science ----because I don't believe such 'laws' can exist ----- but generally, we can say that for every official gesture towards greater tolerance there is almost always a massively angry, if sullenly quiet, popular counter-reaction from about half of the population.
And having an united quietly sullen half of the population on your side is more than enough to get yourself elected -- just ask President-to-be Donald Trump.
