Final answer:
A zero-sum strategy is when one party attempts to win at the expense of the other in politics.
Step-by-step explanation:
The term that describes a strategy in which one party attempts to win at the expense of the other is called a zero-sum strategy.
In politics, a zero-sum strategy refers to a situation where one party's gain is directly proportional to the other party's loss. It is characterized by a competitive approach where one side seeks to maximize its own benefits without considering the mutual interests or positive outcomes for both parties.
For example, if two political candidates are competing for the same position, and one candidate tries to undermine or discredit the other in order to gain an advantage, it would be considered a zero-sum strategy.
