A landslide victory
is an election
result in which the victorious candidate or party wins by an overwhelming margin.
The term became popular in the 1800s to describe a victory in which the opposition is "buried",
similar to the way in which a geological landslide
buries whatever is in its path. What constitutes a landslide varies by the type of electoral system
. Even within an electoral system, there is no consensus on what sized margin makes for a landslide.
