Changing views of college amongst American Republicans

How much of this is Trump and how much of this is the result of Halloween costume email protests at Yale, protesters at the University of Missouri, riots at Berkeley, and the events at Evergreen State College?

The report that the figure comes from notes stark differences between Republicans and Democrats in their views of a lot of institutions. I think that Trump has a lot to do with a generalized distrust but I think that the latter have had a more focused impact on the view of colleges. I wouldn't consider the actions of the protesters there all that representative of academia as a whole (barring certain parts of the university), but they certainly add a lot of fuel to the fire.
