This lecture takes on the question of why we have only two political parties in the United States and how the two party system shapes our politics. Most significantly, this lecture looks at the ways in which the politics of race - Black civil rights in particular - during the Civil War, Reconstruction, the modern Civil Rights Movement and the election of Barack Obama served to shift the two political parties into new realignments. This lecture traces the transformation of the two parties over 150 years, marking the shift of the Democrats from the party of the Confederacy to the party of the New Deal and Civil Rights, and the transformation of the Republicans from the party of Lincoln and Radical Reconstruction to the White Mans Party of Trump.
