Wait, I thought it was November 4, 2008. Or November 2, 2020. Or November 22, 1963. Can't we make up our minds on when the Republic ended? LOL.
January 20, 1989.
Some say our republic ended in 1860, or 1898, or 1913.
November 1932 is when Roosevelt was elected to office. The real major downfall of the Republic was the 17th Amendment, Direct Election of U.S. Senators, that totally destroyed the balance we had between the Feds and the States.
This country, as well as the rest of Western Europe, has been on a downward spiral since the advent of Progressive politics of say 130 years ago.
