Union Home Minister Amit Shah is visiting Tamil Nadu to bolster the BJP's efforts ahead of assembly elections. His visit aims to energize party cadres, refine alliance strategies within the National Democratic Alliance (NDA), and counter rivals. The BJP is working to form a pre-poll alliance, potentially with the AIADMK, amidst challenges including internal divisions within potential allies and the emergence of new political fronts. The ruling DMK alliance appears stable and confident.
