Landslide victory

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. A landslide victory is the opposite of an electoral wipeout; a party which wins in a landslide typically inflicts a wipeout on its opposition.

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.
