The Nevada State Capitol, where its legislature would become the 38th to ratify the 25th Amendment on the afternoon of February 10, 1967.

Once submitted for their consideration, state legislatures took remarkably little time in ratifying the proposed constitutional amendment, realizing it was long overdue.

Nebraska would be the first state to ratify on July 12, 1965, and by the end of that year thirteen states were already on board.  At the end of 1966, that number had increased to 31; and in 1967, sensing that they had opportunity to be the 38th state legislatures would ratify in rapid succession, capped by Minnesota and Nevada, which became the 37th and 38th states on February 10, 1967.  What some perceived as a serious flaw in the Constitution of the United States had finally been corrected.

To commemorate the amendment's ratification, President Johnson presided over a ceremony in the East Room of the White House on February 23, 1967, at which General Services Administrator Lawson Knott officially certified that the 25th Amendment was now part of the United States Constitution, with its principal architect, Senator Birch Bayh, looking on.

Senator Bayh would go on to serve eighteen years in the United States Senate, and would author another amendment to the Constitution - the 26th, which lowered the national voting age requirement to 18 years.  And just as a 34 year old man who would upset a nationally known three-term incumbent to win his seat, in 1980 he would be upset by an even younger man; one whom a decade later would nearly become Acting President himself... 44th Vice President of the United States James Danforth (Dan) Quayle III.
