Before the passage of the 12th Amendment, the candidate who won the most electoral votes was elected president and the candidate who received the second-most electoral votes became vice president. With the rise of political parties, this begins to create problems. The process allowed for a president and vice president with very different political viewpoints. The 12th Amendment allows candidates for president and vice president to run on the same ticket, ensuring similar political views between the two leaders and allowing those in the executive office to work cooperatively.
