# Landslide victory

A landslide victory is an election result in which the winning candidate or party achieves a decisive victory by an overwhelming margin, securing a very large majority of votes or seats far beyond the typical competitive outcome. 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 for one party is often accompanied by an electoral wipeout for the opposition, as the overwhelming support for the winning side inflicts a decisive loss on its rivals. What qualifies as a landslide victory can vary depending on the type of electoral system, as the term does not entail a precise, technical, or universally agreed-upon measurement. Instead, it is used informally in everyday language, making it subject to interpretation. Even within a single electoral system, there is no consensus on the exact margin that constitutes a landslide victory.
A landslide victory implies a powerful expression of popular will and a ringing endorsement by the electorate for the winner’s political platform. Such a decisive outcome can lead the winner to interpret it as a mandate or a tacit authorization from the public to implement their proposed policies and pursue their agenda with confidence. Emboldened by the result, the winner may undertake ambitious reforms or significant policy shifts to reflect the electorate’s desire for meaningful change.
A combination of factors–such as charismatic leadership, a favorable shift in public sentiment driven by dissatisfaction with the status quo, strategic electoral campaigning and a positive media portrayal–can create the conditions necessary for a landslide victory. Such a victory may fundamentally reshape the political landscape of a country, for example Franklin D. Roosevelt's election as US president in 1932. In this imbalanced landscape, the winning party could implement policies more easily, facing little resistance, while the severely weakened opposition may struggle to perform essential checks and balances.

Since 1996, New Zealand has used the mixed member proportional system as in Germany, making landslides much less likely.
First past the post

In 1941, the Nacionalista Party won the presidency, vice presidency, all seats in the Senate, and all but 3 seats in the House of Representatives. This was the biggest landslide in Philippine history. The legislators didn't serve until 1945 though, due to World War II.
Starting in 1987, the Philippines evolved into a multi-party system, and coupled with the introduction of party-list elections in 1998, no party was able to win a landslide, much less a majority of seats, in the House of Representatives since then. This has also meant, until 2022, that no presidential and vice presidential election winner won a majority of votes, although, in 1998, the winners were described as having landslide victories, despite winning less than a majority of votes, due to large winning margins. Senatorial landslides are more possible though in midterm elections, as voters are usually presented with two distinct choices. The 2022 presidential election was the first landslide since 1987.

### United Kingdom

In UK General Elections, a landslide victory involves winning a large majority in parliament and often goes with a large swing from one party to another as well. Landslide victories have usually occurred after a long period of government from one particular party and a change in the popular mood. In the past a majority of over 100 was regarded as the technical hurdle to be defined as a landslide, as that allows the government freedom to easily enact its policies in parliament. In more recent times, the label 'landslide' has been applied in numerous press articles to victories which would not previously have been regarded as such, for example the Conservative Party majority of 80 in 2019. Its current usage is more as political commentary rather than technical definition and is a reflection of the strength of the party's ability to put its programme through parliament.
The largest landslide by any single party in the UK parliament, since universal suffrage was introduced, was the majority of 179 won by Tony Blair's Labour Party in 1997.
