Communist party of India (Marxists), the largest constituent of the Left Front in West Bengal, has never lost an election to Sandeshkhali since 1977. A bastion of CPM, Sandeshkhali had elected a CPM member in 2011. However, the BJP has the potential of cutting into the votes of both TMC and the CPM, thereby upsetting the calculations. An alliance with the Congress may increase the chances of the CPM.
