LBJ guided America through the tragedy of JFK's assassination; he redefined social equality with the Civil Rights Act; he set America's vision toward a "Great Society" with Medicare, Medicaid, education access, and so much more.

In Part 1 of this two-part Season 4 finale, Ryan Rasmussen and Tony Rydberg sift through the good, the bad, and the ugly of one of the most consequential presidencies in American history.
