There’s no mention of anyone saying so at the time, but how pointless and silly would it have been if ratification only required the agreement of the same 2/3 of the states that had proposed the amendment? Might as well not even bother with a second step.
Even so, Wilson’s 2/3 – 2/3 idea nearly passed on the first vote. NH, PA, DE, MD, and VA all voted yes, and MA, CT, NJ, NC, SC, and GA said no. (When he changed it to 3/4, it passed unanimously.) And that was that.
Except…
From what I have seen, pointless and silly is not much of an impediment to the creation of laws.
Impediment? It seems to be more of a requirement.
A 2nd passage is required in some states for some laws. And some laws do get rejected as a result. How many and why [legislature sobered up? election between votes? passed in the first place just to look good?…] are not clear to me.
