Ted Kennedy's political career paralleled the evolution of liberalism in the United States. Here's what writer, professor, and former Secretary of Labor Robert Reich had to say about Kennedy's legacy:
America has had a few precious individuals who are both passionate about social justice and also understand deep in their bones its practical meaning. And we have had a few who possess great political shrewdness and can make the clunky machinery of democratic governance actually work. But I have known but one person who combined all these traits and abilities. His passing is an inestimable loss.
Most Americans will never know how many things Ted Kennedy did to make their lives better, how many things he prevented that would have hurt them, and how tenaciously he fought on their behalf. In 1969, for example, he introduced a bill in the Senate calling for universal health insurance, and then, for the next forty years, pushed and prodded colleagues and presidents to get on with it. If and when we ever achieve that goal it will be in no small measure due to the dedication and perseverance of this one remarkable man. We owe it to him and his memory to do it soon and do it well.
