A very interesting question. I have doubt that any of us know the names of those truly in control. Those kind of people do not want their names known.
The article states that John Kennedy was more conservative than many current Republicans. What were the differences between Republicans and Democrats between 1950 & ‘70? I know that a higher percentage of Republicans voted for the Civil Rights Act of 1964. What were the other differences between the parties? When and why did the Democrats become more liberal? I used google, to find that information, but that didn’t help.
