The correct answer to this open question is the following.
We are talking about the 4th presidential elections in the United States. In that election of 1800, the US Congress had to amend the Constitution so citizens could vote separately for the President and the vice president. The issue was that the members of Congress realized that there was a flaw in the electoral college system. So they had to break the tie between candidates. When US citizens voted, there was no distinction if they voted for the President or the vice president.
