What is the defining feature of dealignment?

Question

Quizplus · Accepted Answer

Dealignment is characterized by a weakening of the traditional allegiance to the two major parties, resulting in a decrease in the percentage of voters who identify with either party. This suggests that the two major parties are losing their relevance to the voting population. A is incorrect because parity (equality) between the parties does not necessarily indicate dealignment. B is incorrect as long-term dominance by one party is not consistent with dealignment, which is marked by a decline in party identification. C is incorrect because a third party emerging to draw attention to their platform can be a result of party realignment, not dealignment. E is incorrect because a group switching its support from one party to another is an example of realignment rather than dealignment.
