Sen. Edward Kennedy's death last week marked the end of a fascinating chapter in American politics. For the past 50 years, Sen. Kennedy honorably served his country and vigorously fought to better the lives of all Americans, leaving a legacy that will live on in America's urban and rural communities for generations to come. He was instrumental in passing many pieces of legislation that have affected the lives of all Americans, including the Immigration and Nationality Act of 1965, the National Cancer Act of 1971, the Federal Election Campaign Act Amendments of 1974 and the Americans With Disabilities Act of 1990. One of the most outspoken and effective advocates for liberal causes in American history, Kennedy will be long remembered for his heroic battles to advance civil rights, universal health care and immigration reform while defending the civil liberties of all Americans. May he rest in peace.
