If you remember Spencer Tracy and Katherine Hepburn, look at the 1948 movie, State of the Union, a story of Tracy running as the Republican candidate for President of the United States against Harry Truman.
In one scene, Hepburn asked the head of the Republican party, “What is the difference between the Republicans and the Democrats?” He replied, “They are in and we are out.”
If you watch the movie you will marvel at the fact that the issues then are the issues now. Things never really change, even though we think they should and we think we can change them.
