A "landslide victory" is a term used to describe a dominating win in an election or any other competitive event. However, it's not the only term used to describe such victories, and there are synonyms that might be more appropriate for certain contexts. For instance, a "crushing victory" or a "resounding victory" both evoke a sense of overwhelming defeat for the opponent. Meanwhile, a "decisive victory" highlights the importance of the win in determining the outcome of the event. A "sweeping victory" implies that the winner has claimed victory in all or most of the contests. Ultimately, the choice of synonym depends on the emphasis one wants to put on the specifics of the event.
