Step-by-step explanation:
The problem that occurred during the presidential election of 1800 was that there was a tie between two candidates from the same party, Thomas Jefferson and his running mate Aaron Burr. This led to the situation being resolved in the House of Representatives. As outlined in the original Electoral College system, each elector cast two ballots, but due to a flaw in the system, Jefferson and Burr received an equal number of votes. The House had to decide in favor of Jefferson after several ballots and the influence of Alexander Hamilton's persuasion against Burr. This tie and its resolution highlighted the problems with the original Electoral College system, which ultimately led to the ratification of the Twelfth Amendment, creating the unified ticket that couples a presidential candidate with their vice president.
