The Twelfth Amendment was ratified in response to tied elections in the Electoral College, specifically exemplified by the Jefferson-Burr tie in 1800, leading to the establishment of separate presidential and vice presidential elections.
The significant problem with the original method of selecting the president and vice president that led to the ratification of the Twelfth Amendment was the occurrence of tied elections in the Electoral College.
