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.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.[5] 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.[6] 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.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.Senate House of Representatives Alberto João Jardim, member of the Social Democratic Party (PSD) was the president of the Madeira region from 1978 to 2015.
