How did the election of 1800 change the method of selecting a president?

It lead to the creation of the Twelfth Amendment, which addresses the issue of choosing the Vice President. The protocol prior to this election was that the and the second-place candidate would be awarded the office of Vice President.However, this system became flawed in 1800, and it became clear that this could not be a permanent system. The Twelfth Amendment was written in order to solve! I Hope I Helped!
