Landon. Roosevelt won 98.5 percent or 523 of the 538 electoral votes up for grabs that year. Such a lopsided presidential election is unheard of in modern history. But Roosevelt's victory is by no means the only landslide White House election. Republican Ronald Reagan won the most electoral votes of any president in history, 525. But that was after seven more electoral votes were added to the prize. His 525 electoral votes represented 97.6 percent of all 538 electoral votes. Definition In presidential elections, a landslide election is generally agreed to be one in which the winning candidate secures at least 375 or 70 percent of the 538 electoral votes in the Electoral College. For purposes of this article, we are using electoral votes as a measure and not the popular vote. It is possible to win the popular vote and lose the presidential race, as happened in the 2000 and 2016 elections because of the way electoral votes are distributed by states. A landslide presidential election, in other words, may not always result in a similarly wide margin in the popular vote because most states award electoral votes on a winner-take-all basis to the candidate who wins the popular vote in their state. Using the standard definition of a landslide victory in presidential politics, when one candidate wins at least 70 percent of the electoral votes, here is a list of contested presidential races that were among the most lopsided in American history. Note: President Donald Trump's 2016 electoral victory does not qualify as a lopsided victory as he won only 306 electoral votes. Democrat Hillary Clinton won 232 electoral votes but carried the popular vote. List of Landslides Under that standard definition, the following presidential elections would qualify as Electoral College landslides: 1996: Democrat Bill Clinton won 379 electoral votes against Republican Bob Dole, who received only 159 electoral votes.1988: Republican George H.W. Bush won 426 electoral votes against Michael S. Dukakis, who received only 111.1984: Republican Ronald Reagan won 525 electoral votes against Democrat Walter Mondale, who got only 13 electoral votes.1980: Reagan won 489 electoral votes against Democrat Jimmy Carter, who got only 49 electoral votes.1972: Republican Richard Nixon won 520 electoral votes against Democrat George S.
