Article IV, Section 4, Clause 1:
“The United States shall guarantee to every State in this Union a Republican Form of Government.”
... which is impossible to do without integrity of elections, as they are essential to having a republican form of government.
Wow. Well thats a stretch. I have an idea. Since we’re going down that route, how about the Federal Government supply all voting equipment, therefore standardizing elections in each state? And, while we’re at it, to further simply things, why don’t we make voter registration a Federal responsibility instead of a State responsibility?
You down for those changes? Seems to fit your mindset.
That actually mandates that the federal government ensures the integrity of the vote in each and every state. Right there in the Constitution. The states have no legal grounds on which to refuse this request because of it.
