Rather than going into any introduction let me straight get into some inferential conclusions
The immensity of loss is not only because Congress became too popular, or BJP because too unpopular. The vote percentage of BJP remains same suggests that BJP’s core votes remain where it was and have not moved. Congress has increased its vote share because JDS has lost equivalent vote share.

The shift of Votes from JDS has happened due to consolidation of Muslim votes. So Pasmanda strategy has not worked

GRAND Conclusion
FOCUS on consolidating 85% rather than on 15% because 15% is never yours
