Election Mechanics · Fixed a real design flaw that nearly broke the 1800 election
Ratified in 1804, the Twelfth Amendment requires separate electoral votes for President and Vice President — a direct response to a genuine constitutional crisis in the election of 1800, when the original system produced a tie between running mates.
The Electors shall…vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves.

What Actually Went Wrong in 1800
Electors originally cast two votes for President, full stop
Under the original system, each elector cast two votes, both for President — the runner-up simply became Vice President. Once organized political parties emerged, with running mates intended for separate offices, this created a real problem: in 1800, Thomas Jefferson and his own running mate Aaron Burr tied with the same number of electoral votes, throwing the election into the House of Representatives for 36 rounds of voting before Jefferson finally won.
This amendment exists because of a problem the framers never anticipated
A common misconception is that the original Constitution’s electoral system was designed with organized political parties and running mates in mind. It wasn’t — the framers largely didn’t anticipate the rise of formal party tickets, and the original electoral college design assumed electors would exercise independent judgment about two separate, unaffiliated candidates. The 1800 crisis is a direct result of political reality outpacing the document’s original design.
