Viswanathan is viewed as a veteran AIADMK leader with strong roots in Natham constituency, having won multiple elections since 1999. However, his political fortunes are tied to AIADMK's broader challenges including internal party strife, controversial BJP alliance, and the party's struggle to regain relevance after consecutive electoral losses.
