I don’t believe that, even in the face of a full coup, (gun) violence will solve any issues. There’s just no way that a majority of people support a violent militia taking over power of the government, no matter how illegitimate some think that government is.
As examples, look at the recent coup attempt in Turkey, or the Wagner uprising in Russia. In both cases the violent uprisings were used by the dictator to cement his power. Guns will not help you.
That’s a very interesting poll because in the end HRC got 48 percent of the vote, or 2 percentage points more than in this poll, while DT got 46 percent, 11 percent more than in the poll. One explanation could be that undecided, Johnson and Stein voters changed their minds and (mostly) voted for Trump.
