What Clinton's Historic Nomination Means For Democratic Party And The Nation

After Tuesday night, Hillary Clinton is now officially the Democratic nominee and the first woman ever to head a major party ticket in the U.S.

As music played on the convention stage in Philadelphia, she addressed the crowd by video feed from New York: "I am so happy. It's been a great day and night. What an incredible honor that you have given me. And I can't believe we just put the biggest crack in that glass ceiling yet."

Massachusetts Congresswoman Niki Tsongas is at the convention in Philadelphia. She spoke with WBUR's Morning Edition about what this historic nomination means for the Democratic party and the nation.
