Landslide Victories

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.

Notable examples

Much of this 32 year period was under 7-term Premier Joh Bjelke-Petersen. In the election, Labor won 50.3% of the primary vote and 53.8% of the two-party preferred (TPP) vote, and 54 out of 89 seats, despite a system of malapportionment which was designed to keep the Country Party in power.

Federal elections:

* 1966 Australian federal election – PM Harold Holt leads his incumbent Coalition Government (now consisting of the Liberal Party and Country Party) to a landslide victory over the Labor Opposition, increasing their majority by a further 10 seats, the Liberals almost won enough seats to govern in their own right without the Country Party.

* 2007 Australian federal election – Labor led by Kevin Rudd wins landslide victory over Coalition Government led by PM John Howard who had been in office for 11 consecutive years. Not only did the Coalition lose government but John Howard lost his seat.
Notable non-landslides:
* The 1972 Australian federal election resulted in a victory for Labor under Gough Whitlam, ending 23 consecutive years of Coalition government. However, the result was not a landslide with Labor only winning 67 of 125 seats.
* The 2018 Australian federal election, whilst polls showing a Labor victory, was won by the Coalition. The elected Prime Minister, Scott Morrison, became the first to serve a full term in office (serving one and a half terms) since John Howard.

It was a historic loss for the Coalition, which was reduced to just 58 seats of 151 seats, their worst result in 70 years. However, Labor only won a slim majority, 77 of 151 seats. This is because the Coalition losses were split between Labor, teal independents and the Greens, while Labor themselves also lost seats to independents and Greens.

Philippines

In 1941 Philippine general election, 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 won'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 representation in the House of Representatives of the Philippines, 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 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.
