Very well analysed and written sir.The reasons for victory of BJP on 47 seats out of 90 seats contested is far below their lead in parliamentary seats on 53 seats out of 72 contested. Thus their popularity and acceptability in the state voters has decreased considerably even within a short span of few months between the parliamentary and assembly elections.
But credit goes to the party high command descending on Haryana with many of the central ministers led by Modi to Haryana during the election campaign and their success in convincing the people to vote for same party at centre and state ruling and influencing floating votes in favour of their party on promises made in public utterances and manifesto declarations. They had larger means to control space in advertising the Modi Model of development in comparison to other parties. Though Hooda government tried to sell out their development model through media, even then the Congress could not match their campaign management during the last leg of elections. INLD and other regional parties proved lesser entities in this respect.
This is one of the major cause of the success of BJP. The cause of failure of other parties to rise to the occasion are many and varied which could come out on deeper individual party role analysis.
