The Fourteenth Amendment, changed one from being a citizen of a State as well as a citizen of the United States to being either a citizen of a State or a citizen of the United States. In addition, under Section 1, Clause 1 of the Fourteenth Amendment, one who is a citizen of the United States can become also a citizen of a State by residing in a State, that is, a citizen of the United States and a citizen of a State. Under Article IV, Section 2, Clause 1, a citizen of a State is now a citizen of the several States, that is, a citizen of a State as well as a citizen of the several States. So in every State in the Union, there are two state citizens; a citizen of the United States under Section 1, Clause 1 of the Fourteenth Amendment and a citizen of the several States under Article IV, Section 2, Clause 1 of the Constitution. And, under the Constitution of the United States (of America) there are two citizens; a citizen of the United States, at Section 1, Clause 1 of the Fourteenth Amendment and a citizen of the several States at Article IV, Section 2, Clause 1.
