This week at In The Past Lane, the American history podcast, I speak with author Larry Tye about his new book, "Bobby Kennedy: The Making of A Liberal Icon" (2016, Random House). Tye is eager to dispel is the notion that there were two, polar opposite Bobby Kennedys - the bad boy in the 1950s who worked for Sen. Joseph McCarthy and later waged war on organized labor and the saintly good guy in the mid-1960s who fought for social justice.
