Language, Power, and Opposition: A Critical Discourse Analysis of Online News Headlines on ADC-Led Party Mergers Against Tinubu’s Reelection Bid

This study examines how Nigerian online news headlines discursively construct emerging opposition party mergers led by the African Democratic Congress (ADC) ahead of the 2027 general elections. Although previous research in Nigerian political communication has focused on election-day reporting and campaign rhetoric, little attention has been given to preelection discourse or to how headlines shape public perceptions of alternative political blocs before formal campaigns begin. To address this gap, the study applies Norman Fairclough’s three-dimensional model of Critical Discourse Analysis (CDA), which enables an examination of how textual features (lexis, modality, transitivity), discursive practices (news routines, sourcing, digital circulation), and sociocultural contexts (media ownership, ideological alignments, political economy) interact to construct meaning and reproduce power relations. Using a purposively selected corpus of 100 headlines published between March and September 2025 across six nationally influential online platforms, the study investigates how linguistic strategies frame the legitimacy, cohesion, and viability of the ADC-led merger movement. Findings show that headlines predominantly depict the mergers as unstable, fragmented, or politically insignificant, thereby delegitimizing opposition actors and reinforcing incumbent advantage. These discursive patterns reflect broader sociopolitical structures, demonstrating how headline discourse functions as an ideological instrument that shapes public perception and restricts democratic plurality.
