The 14th is fraudulent.
That’s a personal opinion.
The facts are that in the 142 years since the 14th Amendment was ratified, there has been NO attempt to ratify another amendment to invalidate the 14th.
When the People decided that they didn’t want the 18th Amendment any more, the elected representitives of the people in our Republic passed the 21st Amendment to render the 18th Amendment moot.
That could be done with the 14th, but it hasn’t been attempted.
Since the 14th Amendment was declared to have been officially ratified by Secretary of State William H. Seward in 1868, an additional 13 states have ratified it. The latest being the states of New Jersey and Ohio in 2003.
