Dr. Jerold Duquette is a Professor of Political Science at Central Connecticut State University. After a Bernie Sanders supporter shot Republican Congressman Steve Scalise, Duquette tried to place some of the blame on Donald Trump. He said, "Donald Trump is corrupt, dishonest, and stupid. Intellectually feeble and mentally unstable people drawn to political extremism have and will be inspired or driven by Trump and trumpism to say and do horrible things. Yesterday, a left wing extremist was driven by Trump and trumpism to try to kill people."
