I disagree with Michael Cohen right off the bat in his lecture about Nelson Rockefeller. Nelson wasn’t a Moderate, but was a Progressive and a Progressive Republican. Progressives in the real sense might look like Moderates compared with Socialists on the Far-Left who expect the national government to do practically everything for people. And in the case of Communists, want the national government to literally do everything for everybody. Perhaps even check people’s shoes to make sure they’re tied correctly before the central government allows for people to leave their homes. And Libertarians on the Right and if you’re talking about Anarchists on the Left, who don’t want government to do anything for everybody. That government in any form is corrupt and incompetent, and a form of enslavement.
Michael Cohen made my point that Nelson was a Progressive in his own lecture when he said that Rockefeller was a doer. He believed in government and that government can create positive change and do positive things for people. What do Progressives believe? They believe that progress can be made through government action. Limited government action since Progressives aren’t Socialists or Communists, and there not even Liberals. Less ideological than Liberals and really everyone who is not a Moderate or Centrist and stress individual rights and individualism less than Liberals.
By the time 1968 comes around Richard Nixon essentially takes over the Republican Party in order to not just win the presidential election, but to serve him politically. By campaigning strongly for Congressional Republicans in 1966 and contributing to their comeback both in the House and Senate and making the GOP players in Congress again. But also by campaigning in the South that was traditionally Democrat, but Dixiecrat and even Confederate, and even religious as far as how they looked at their politics. What we today call the Christian-Right comes to the Republican Party by the late 1960s thanks to Richard Nixon and others. With Northeastern Republicans leaving the GOP except for Nelson and a few others and become Democrats. Which left Nelson Rockefeller without a major political party to run for president for.
