This study aims to explore the impact of cross-carpeting in the political system and provide a feasible solution to Nigeria's high rate of party turnover. The corporate existence and Democratic Consolidation in Nigeria have been significantly tarnished by crosscarpeting. Party defection, cross-carpeting, party switching, and other terms that describe this phenomenon have grown so commonplace in Nigeria that the typical Nigerian views them as both a tradition and an essential component of democracy. Unhealthy power struggles and internal party strife do result from this. In Nigeria, the rate at which party members switch from one political party to another has denigrated and ridiculed the party system. In addition to being portrayed as lacking morality and integrity, the scenario shows Nigerian politicians as self-serving self-aggrandizers. The effect of party defection on the consolidation of democracy was explained by the study using the Group theory. Most of the study's foundation comes from secondary data sources, including an extensive examination of pertinent books, journals, magazines, newspapers, government publications, historical records, and online resources. The results show that although party alignment is not joint, cross-carpeting has become a severe problem and significantly hinders Nigeria's democratic consolidation. The study concludes with recommendations for politicians to cease indiscriminate party switching and for political parties to be founded on robust ideological bases, thereby enhancing the quality of Nigeria's democratic processes.
