Krishnagiri constituency witnessed significant political and developmental activity between 2021 and 2026. K. Ashok Kumar of AIADMK won the seat in the 2021 assembly elections by a narrow margin of just 794 votes against DMK's T. Senguttuvan. The constituency benefited from substantial infrastructure investments during this period, including the expansion of the Hosur-Krishnagiri National Highway from four to six lanes, rural road improvements under PMGSY, and healthcare initiatives like the Makkalai Thedi Maruthuvam scheme launched in March 2026 for door-to-door health services. In March 2026, Prime Minister Modi inaugurated projects worth ₹5,650 crore across Tamil Nadu, including rural road expansions and new train services. The district, being part of the Chennai-Bengaluru Industrial Corridor, continued to see industrial growth through Hosur SIPCOT and Krishnagiri SIDCO. However, the constituency faced civic challenges including severe flooding and waterlogging due to poorly maintained drains and garbage management issues, with Swachh Bharat vehicles being misused for mixed waste collection instead of segregated waste. The period also saw significant political turmoil at the state level with multiple AIADMK leaders being expelled and joining DMK. In the 2024 Lok Sabha elections, Congress candidate K. Gopinath won the Krishnagiri parliamentary seat with a decisive margin of 192,486 votes, indicating a shift in political sentiment. As voters approach the scheduled April 23, 2026 assembly elections, they should consider both the developmental progress achieved and the persistent civic issues that need resolution.
