"We all remember well known examples of what an ill-advised shift from liberal to conservative leadership can do to an incompleted liberal program. Theodore Roosevelt, for example, started a march of progress during his seven years in the Presidency but, after four years of President Taft, little was left of the progress that had been made. Think of the great liberal achievements of Woodrow Wilson's New Freedom and how quickly they were liquidated under President Harding. We have to have reasonable continuity in liberal government in order to get permanent results."
