You have little or no understanding of what a “Republican” was in 1970, or of what a “Democrat” was in 1970. Things were very different then. The main difference was the war in Vietnam. There was a lot of agreement on many other issues, and there were many very conservative Democrats and many liberal Republicans still in Congress.
democrats have always been socialists/Marxists.
FDR a democrat and his democrat Congresses imposed upon America a lot of socialist laws including the New deal.
This was in the 1930’s.
You really think all these hundreds of thousands of pages of government regulations don’t cripple American manufactuers and businesses. Government/socialism doesn’t work: Just look at the TSA stooges.
