In retrospect it seems everything he warned about has come true.
According to his Wikipedia biography, Gilbert Livingston (1742-1806) did in the end vote for ratification of the Constitution because he felt confident that a bill of rights would be added. He was from a less affluent branch of the prominent Livingston family of New York. His son-in-law Smith Thompson became an associate justice of the Supreme Court (after Gilbert’s death).
The members of this site would do well to study the Founding Fathers’ speeches, writings, sermons, etc., including what we now call the Congressional Record. There is nothing new under the sun.
I refer to books written by David Barton of Wallbuilders. He is an excellent scholar in this area. First recommendation is a book titled Original Intent.
Thanks to the 17th Amendment.
