In 2009, Adlai Stevenson III spoke with Carol Marin on “Chicago Tonight.” Even though he was a self-proclaimed “reformer,” he still found virtues in the old party machinery. Stevenson died Monday at the age of 90.

We speak with former senator and gubernatorial candidate Adlai Stevenson. He left the Democratic Party to run as a third-party candidate in 1986 because of problems with that year's candidate for lieutenant governor.
