On this edition of "Political Rewind," "Hardball" host Chris Matthews joins us to discuss his new book, which offers fresh insights on the life of Robert Kennedy. Matthews sees Kennedy as a shining example of the kind, moral leader he thinks is absent from the political scene today. Also, we’ll look at the latest developments in Alabama and in Washington in the ongoing Roy Moore controversy. Despite increasing pressure, Moore seems determined to say in the race. Plus, Hillary Clinton tells a packed house in Atlanta that Trump fever has broken and the tide is turning.
