It was in the 14th...
They took any power that the states thought they had in section 1, and gave congress the authority to regulate it by statute in section 5.
This effectively isolated the Constitution from any state bullshit. it also reminded congress of their responsibility to manage naturalization.
I did not think it was Gobbledygook.
BTW, as you know...I guess...the natural born language was in article 2. They did not explain it, define it or give congress authority to naturalize.
The 14th gave congress the role of naturalization as they were expecting a heard of immigrants. But they still had not defined natural born and have not.
This was not passed until 1868.
