Former Pennsylvania senator Arlen Specter was quite a character. Hard-edged and sometimes difficult, Specter was at the center of the Senate’s legal battles for years as a ranking member of the Judiciary Committee – particularly Supreme Court nominations. He also had a large independent streak, which led him to announce that he was switching parties and becoming a Democrat in 2009. The move cost him his Senate seat. He died on Sunday at the age of 82 of complications of non-Hodgkin’s lymphoma. He was on the Leonard Lopate Show in 2008 and he told Leonard about his earlier battle with Hodgkin’s disease and his long career in the Senate.
