President Donald Trump called for unity and working together during his State of the Union Tuesday night after a year of often deep divides and partisanship in the White House and on Capitol Hill. Colgate University assistant professor of political science Dr. Sam Rosenfeld has written a book entitled "The Polarizers: Postwar Architects of Our Partisan Era” which looks at the unyielding political climate of today.
Rosenfeld tells WAMC’s Brian Shields the president’s troubles with his fellow Republicans began to take shape well before inauguration day in 2017.
