It's odd to me that someone who's worried about intellectual debate becoming rare would vote for Trump. Trump avoids substantive debates and relies on catch phrases. It seems to me that the lack of intellectual debate is tied to polarization of political parties rather than anything done by the Obama administration.

And there is real evidence that the republican party is driving the lack of real debate. The republican party refused to allow hearings for a Supreme Court nominee for a legitimately elected sitting President. That's obstructionism driven to ignoring the constitutional duties granted to the President to achieve political ends.
