The 12th amendment requires?

The 12th amendment to the United States Constitution requires the separate designation of electoral votes for President and Vice President. It was ratified in 1804 and created a separate electoral college vote for each office, rather than the previous system where the candidate with the most votes became President and the runner-up became Vice President. The amendment was introduced to avoid conflicts and confusion in the electoral process and to ensure a more balanced and deliberate selection of both the President and Vice President.
