Imagine the Congress and the BJP in a tennis match, circa January 2018. The Congress is on the verge of being eclipsed in a fierce encounter. Translocate the scoreline to the political court. Karnataka, Puducherry and Punjab are the only states with the party. Yet, by the time the year ends, the Congress has fought back fiercely, managing to stall the BJP, and winning three big states (Madhya Pradesh, Rajasthan and Chhattisgarh) besides retaining Karnataka, albeit in a coalition.
