As soon as definitive trends from the Karnataka Assembly polls came out, Bharatiya Janata Party (BJP) Chief Minister Basavaraj Bommai conceded defeat to the Congress and promised that the party would learn from its mistakes and plan for the Lok Sabha polls of 2024. For the BJP, these polls in Karnataka were just as existentially important as for the Congress as the State was its only bastion in southern India, and its presence there was a strong argument to fight the perception of the BJP being a Hindi-speaking party. The loss in Karnataka will hit the BJP in terms of the perception of it being a largely north Indian party, out of touch with the political and cultural sensibilities of the southern States, and some of the messages from the Chief Ministers of southern States have touched upon those themes.
The State unit of the BJP in Karnataka may well say that they will learn from the mistakes and the party may well do as well as it did the last time around in Karnataka in the Lok Sabha polls (when the party won 24 out of 28 seats) due to the immense popularity of Prime Minister Narendra Modi in the State, but for the national leadership, the problem goes beyond that.
