Political polarization in the context of "Center squeeze"

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. A landslide can be viewed by a winning candidate or party 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. However, it can also indicate deep political polarization in an electorate or an unfair election.

Political communication is the study of political messaging, e.g. in political campaigns, speeches and political advertising, often within the mass media. It is an interdisciplinary subfield located between communication studies and political science. Political communication is concerned with ideas such as information flow, political influence, policy making, news, and public opinion. The field also focuses on the study of political social media, propaganda, political economy of communication and non-profit organisations that communicate to affect political processes. Modern societal changes that have affected the field include the digitization of media, polarization and a movement towards a post-truth media environment.

Salvador Allende was the president of Chile from 1970 until his suicide in 1973, and head of the Popular Unity government; he was a Socialist and the first Marxist elected to the national presidency of a liberal democracy in Latin America. In August 1973 the Chilean Senate declared the Allende administration to be "unlawful," Allende's presidency was ended by a military coup before the end of his term. During Allende's three years, Chile gradually transitioned into a socialist state.

During his tenure, Chilean politics reached a state of civil unrest amid political polarization, hyperinflation, lockouts, economic sanctions, CIA-sponsored interventionism and a failed coup in June 1973. Allende's coalition, Unidad Popular, faced the problem of being a minority in the congress and it was plagued by factionalism.

Ultraconservatism refers to extreme conservative views in politics or religious practice. In modern politics, ultraconservative usually refers to conservatives of the far-right on the political spectrum, comprising groups or individuals who are located to the right of those who hold mainstream conservative views, and continuing further right to include fringe parties.

Elements of ultraconservatism typically rely on cultural crisis; they frequently support anti-globalism – adopting stances of anti-immigration, nationalism, and sovereignty – and use populism and political polarization, with in-group and out-group practices. The primary economic ideology for most ultraconservatives is neoliberalism.

A culture war is a form of cultural conflict (metaphorical war) between different social groups who struggle to politically impose their own ideology upon mainstream society, or upon the other. In political usage, culture war is a metaphor for "hot-button" politics about values and ideologies, realized with intentionally adversarial social narratives meant to provoke political polarization among the mainstream of society over economic matters, such as those of public policy, as well as of consumption. As practical politics, a culture war is about social policy wedge issues that are based on abstract arguments about values, morality, and lifestyle meant to provoke political cleavage in a multicultural society.

Fake news or information disorder is false or misleading information (misinformation, disinformation, propaganda, and hoaxes) claiming the aesthetics and legitimacy of news. Fake news often has the aim of damaging the reputation of a person or entity, or making money through advertising revenue. Although false news has always been spread throughout history, the term fake news was first used in the 1890s when sensational reports in newspapers were common. Nevertheless, the term does not have a fixed definition and has been applied broadly to any type of false information presented as news. It has also been used by high-profile people to apply to any news unfavorable to them. Further, disinformation involves spreading false information with harmful intent and is sometimes generated and propagated by hostile foreign actors, particularly during elections. In some definitions, fake news includes satirical articles misinterpreted as genuine, and articles that employ sensationalist or clickbait headlines that are not supported in the text. Because of this diversity of types of false news, researchers are beginning to favour information disorder as a more neutral and informative term. It can spread through fake news websites.

The prevalence of fake news has increased with the recent rise of social media, especially the Facebook News Feed, and this misinformation is gradually seeping into the mainstream media. Several factors have been implicated in the spread of fake news, such as political polarization, post-truth politics, motivated reasoning, confirmation bias, and social media algorithms.
