Is there a clear north-south divide in Indian politics?

After its loss in the recent Assembly elections in Karnataka, the Bharatiya Janata Party is left with no State government in south India. It is part of an alliance in the Union Territory of Puducherry. The governments of the five States of the south are led by different parties — the Dravida Munnetra Kazhagam in Tamil Nadu, the Communist Party of India (Marxist) in Kerala, the YSR Congress Party in Andhra Pradesh, the Bharat Rashtra Samithi in Telangana, and the Congress in Karnataka. This is not a new trend; the south has rarely followed the electoral trend set by the north. In the 1977 Lok Sabha elections, while the Congress was wiped out in the Hindi heartland, it continued to hold onto its seats in the south. Similarly, in the last nine years, even at the peak of its popularity the BJP has been unable to breach the southern fortress as convincingly as it would like to.  Is there a north-south divide in politics?
