Core issue

The article analyzes the recent by-election results in Tamil Nadu for the Madurantakam and Dharapuram Assembly constituencies, both reserved for Scheduled Castes (SCs). It highlights the victories of the ruling Tamilaga Vettri Kazhagam (TVK) and the factors contributing to them, including the Chief Minister C. Joseph Vijay's intensive personal campaign, party realignments, and caste dynamics. Despite the wins, the article notes that the results were not overwhelming for the TVK, with vote shares not exceeding 40%, and the DMK retaining a significant vote bank. It discusses the challenges faced by the traditional Dravidian parties (DMK and AIADMK) and the potential shift in the state's political landscape from a duopoly, while also emphasizing the traditional trend of by-elections favoring the ruling party.
