1824: Andrew Jackson vs John Quincy Adams|
In this election, Andrew Jackson received 44,804 more popular votes than John Quincy Adams.
1876: Samuel J. Tilden vs Rutherford B. Hayes
Popular Vote Totals Jackson (153,544) John Quincy Adams (108,740)
Andrew Jackson also received the most electoral votes, 99, but he did not receive the required 131 majority.
According to the Twelfth Amendment, when no candidate obtains a majority of electoral votes, the election is decided by the House of Representatives, which gave John Quincy Adams the majority of electoral votes and therefore the Presidency.
This provoked great bitterness for Jackson and his supporters, who proclaimed John Quincy Adams' election a "corrupt bargain".
The 1876 election was one of the most controversial presidential elections in American history.1888: Grover Cleveland vs Benjamin Harrison
Governor of New York, Samuel J. Tilden received 252,666 more popular votes than Rutherford B. Hayes, Governor of Ohio.
Popular Vote Totals Tilden (4,286,808 or 50.92%) Hayes (4,034,142 or 47.92%)
Tilden won 184 electoral votes (needing just one more for a majority) and Hayes received 165, leaving 20 disputed electoral votes in four states. Three states had all of their electoral votes unresolved: Florida (4), Louisiana (8), South Carolina (7) but only 1 of Oregon's 3 electoral votes was disputed.
The Democrats needed just one more electoral vote for the Presidency, but in essence, they were quite willing to relinquish the Presidency in exchange for the end of Reconstruction in the South and returning the South to its antebellum politics. So, they struck a deal with Congress (the Compromise of 1877), which outright gave all 20 electoral votes (and the Presidency) to Hayes. In return, Hayes officially ended Reconstruction and withdrew all federal troops from the Southern states.
Tilden lost the election by one electoral vote and Hayes' detractors referred to him as "Rutherfraud", "His Fraudulency" and called the Compromise of 1877 a "corrupt bargain". (Does "corrupt bargain" sound familiar? See the election of 1824.)
As for the long-term results of this election?
The election of 1876 completely ended the era of Southern Reconstruction.
With less federal pressure on the southern states (particularly with the removal of federal troops), these states passed laws which led to the disenfranchisement of black voters. Other laws were passed which were deliberately designed to separate white and black people in schools, restaurants and so on. These laws remained in effect until the civil rights movement of the 1960's brought these to an end.
The 1888 election saw Democratic President Grover Cleveland from New York trying to secure a second term against Republican Benjamin Harrison a former U.S. Senator from Indiana.
Popular Vote Totals Cleveland (5,534,488 or 48.63%) Harrison (5,443,892 or 47.80%)
Cleveland's Popular Vote Lead Was 90,5962000: Vice President Al Gore / Senator Joe Lieberman
In many states, the popular vote was extremely close (about 1%), most notably New York, where the Tammany Hall political machine was extremely powerful.
When Grover Cleveland was Governor of New York, he fought political corruption especially Tammany Hall.
Now that Cleveland needed the 36 New York electoral votes, Tammany Hall helped deny Cleveland those votes of his home state.
Although Cleveland had the popular vote plurality, his 168 electoral votes to Harrison's 233, made Benjamin Harrison the President.
Had those votes gone to Cleveland instead of Harrison the final electoral vote total would have been Cleveland 204, Harrison 197 and Cleveland would have been re-elected.
George W Bush, Governor of Texas / Dick Cheney
This election concluded in Florida, where a very narrow difference in votes triggered a mandatory recount as well as additional recounts ultimately reaching the United States
