What would happen if they gave an election and no one voted?
Have you ever wondered why you must be a "federal citizen" to vote? That's what a U.S. Citizen is by the way. Check it out in Black's. Do you live on federal territory/land/vessel? Are you a federal employee? The chances are you aren't really a U.S. Citizen, but since it's presumed that you know what you're doing and you go around filling out forms and telling folks you are a U.S. Citizen when they ask, then they have the basis for their presumption (albeit a rebuttable one) that you belong on their plantation.
The point in case here is that the United States State Department has been issuing passports to those born in the various states of the Union, but by affidavit they are claiming they are not U.S. Citizens (ala the fraudulent 14th Amendment, btw) and are instead non-citizen nationals or in essence state nationals.
