The story of liberalism isn't often told, especially as the conservative era has taken root. Yet, there was a key figure in the formation of modern-day liberalism who is indeed worthy of attention: the late Sen. Edward “Ted” Kennedy.

Historian and writer Neal Gabler joins Julian Zelizer and Sam Wang in this week’s episode to discuss the early part of Ted Kennedy’s career. Gabler is the author of “Catching the Wind,” the first installment of a two-part volume on Ted Kennedy’s achievements, which include sponsoring nearly 700 bills that eventually became laws.

Gabler is the author of several books, and his essays and articles have appeared in The Atlantic, Vanity Fair, Esquire, Playboy, Newsweek, and Vogue, and more. He is currently a professor for the MFA program at Stonybrook Southampton.
