Answer:
The election went to the House of Representatives and led to an amendment to the Constitution.
Step-by-step explanation:
In the US presidential election of 1800 sometimes called "The Revolution of 1800", Thomas Jefferson turned to John Adams.
The members of the electoral college could vote only for the president, in such a way that the vice president would be the person with the second highest number of votes. The Democratic-Republican plan in favor of Jefferson and not Aaron Burr, who was second in the party, was botched and the result was a tie in the electoral vote. That was when the election was placed in the hands of the House of Representatives of the Federalist Party. The majority voted to block Jefferson from the presidency.
As a result, the 12th amendment, ratified in 1803, was added to the US Constitution, allowing electors to elect the president and vice president.
