Two errors; first the typo; Mondale ran in 1984, not 1884.

And Jackson didn't lose in the Electoral College to JQ Adams. The results for that race were:

John Quincy Adams (MA) 84 115,696
Henry Clay (KY) 37 47,136
Andrew Jackson (TN) 99 152,933
William H. Crawford (GA) 41 46,979

Jackson had the most popular votes and the most Electoral votes, but didn't have anywhere near a majority of either due to it being a race with four significant candidates. Note that Clay was actually the one messed with by the popular/Electoral difference, as he had more popular votes than Crawford, but fewer Electoral (although they were very close to a dead heat). That's significant, since the 12th Amendment handles the situation of no candidate getting an Electoral majority by tossing it to the House...who only get to choose between the top three Electoral vote winners. Clay, who was Speaker of the House, was thus eliminated. He threw his support and influence within the House to Adams, who thus won as a result of a vote of the House, not due to either Electoral or popular vote wins.
