Why Analysts are Surprised by Sandeep Pathak’s Move to BJP: The Fall of Kejriwal’s Key Strategist

The decision of Sandeep Pathak, a top strategist for the Aam Aadmi Party (AAP) and a Rajya Sabha MP, to join the Bharatiya Janata Party (BJP) is being hailed as one of the biggest shocks in Indian politics. There is profound astonishment in political circles over how Arvind Kejriwal’s most trusted ‘Chanakya’ suddenly switched sides. Pathak was not just an MP; as the National General Secretary (Organization), he was considered the backbone of the party’s entire operational structure. His defection, along with six other Rajya Sabha MPs including Raghav Chadha and Swati Maliwal, signifies more than just a change of heart—it signals a potential collapse of AAP’s organizational framework. Analysts view this as a personal and strategic loss for Kejriwal that may be impossible to recover from in the near future.

Pathak’s profile makes him a unique figure in politics, which is why his move has stunned experts. A former professor at IIT Delhi with a PhD from Cambridge University, Pathak is regarded as a master of data and electoral statistics. He was the architect behind AAP’s landslide victory in Punjab and the strengthening of the organization at the booth level in Delhi. Analysts believe his move to the BJP indicates a deep ideological and strategic rift within AAP. Sources suggest that after losses in the 2024 Lok Sabha and the recent 2025 Delhi Assembly elections, the distance between Pathak and Kejriwal had grown, with questions being raised about his working style and candidate selections.

For the BJP, gaining Sandeep Pathak is akin to hitting a jackpot. Pathak possesses confidential knowledge of AAP’s entire organizational machinery and a deep understanding of electoral data, which the BJP can now leverage to gain ground in Punjab and Delhi. Furthermore, because seven out of ten MPs moved together, the transition technically falls under the category of a ‘merger,’ making it difficult to take action against them under the anti-defection law. Political pundits say that the departure of such a quiet, behind-the-scenes strategist sends a message that Kejriwal is running out of the reliable shoulders that once gave the party its national identity.
