Then his tear jerking speeches pleading for a more civil discourse and culture?
“Obama Calls for a New Era of Civility in U.S. Politics”

Then he turns around and criticizes Trump for the violence at his rallies when it was Obama, Hillary and the democrats who were inciting the violence with paid thugs.
