Which president won the presidency without winning the popular vote?

Grover Cleveland is a notable figure in American presidential history for winning the presidency without securing the popular vote. He is the only president to serve two non-consecutive terms, first winning in 1884, then losing in 1888, and winning again in 1892. In the election of 1888, despite winning the popular vote, he lost the Electoral College to Benjamin Harrison, who won the presidency. This situation highlights the unique characteristics of the Electoral College system, where a candidate can win the presidency by securing a majority of electoral votes while not necessarily winning the nationwide popular vote. Such occurrences have led to discussions on the effectiveness and fairness of the Electoral College in representing the will of the people.
