There’s no such thing as a “federal election”. Elections are run by the States; specifically the Legislatures of the several States.
Remember: when you go to cast your ballot you’re not voting for “Smith” for President. You’re voting for a slate of electors pledged to “Smith”, and you’re doing so only because your State Legislature chose to allow you that privilege.
The closest thing we have to a “federal election” occurs when the Electors chosen by the several States meet to cast THEIR votes.
Ummmm states have jurisdiction over all elections. We are the United States of America. Not the United state of America.
Scary question to read on a conservative forum.
How does State government have jurisdiction over a Federal election?
Kind of like states legalizing marijuana
