BJP on its own strength did not win the elections. it joined hands with socialists, trinamul congress,BJD , National conference and TDP and DMK or AIADMK. it had alliances with all parties in every state. thus it came to power and it is not BJP government but NDA government.
Vajpayee succeeded in managing his government for five years by distancing himself from controversial matters.
Due to not a wise propaganda that India is shining, though farmers committed suicide due to drought, and due to the unrest among the people against BJP's allies, it had been defeated in 2004.
from the defeat of 2004, the BJP did not learn any lessons. instead of strengthening its cadre, it heavily relied on its alliance parties like JD(u), DMK, Trinamul congress and BJD. these parties realized that the winning chances of BJP are bleak switched their loyalties and thus made BJP a lone party to carry on the battle in 2009, though JD(u) , was for the name sake remained as its partner, it did not allocate many seats to it in Bihar.
The retirement of Vajpayee, who had pan India appeal, paved way for the eclipse of the BJP in Indian politics. internal squabbles , relying on capitalists and ditching its committed swadesi economists and ideologues like Govindacharya, Gurumurthy and coming close to mining mafia in karnataka and its non democratic behavior in parliament, expulsion of its members for cash for questions scam, made it a deadwood.
another factor that contributed to the defeat of BJP was the Mayawathi factor in UP which state sends more MPs and Rahul Gandhi's factor in UP who boosted his party in the UP.
Social psychologists say, India or any other country in the world does not accept extreme left and extreme right parties. People prefer center of right or center of the left. the same thing happened in India. the US, and other Latin American countries.
In near future, i firmly believe the future of so called communists and right wing elements like BJP and Sivasena is bleak unless they collaborate with any party for the sake of power.
The psycho analysis of the BJP tells us the causes of its debacle. its committed cadre are not happy with it diluting Hindutwa philosophy and Swadeshi economy and they could not digest the NDA's policies appeasing the American government and National conference in Kashmir. they were disappointed as no Ram Mandir was constructed in Ayodhya. Edit . If the BJP follows Hindutwa policy, it would be isolated because no other party in the country openly support Hindutwa policy . Thus it is under catch 22 situation.
In psychology this type of situation is called "approach avoidance conflict".
Another thing is , it miserably failed in safeguarding the interests of north Indian people. it did not launch any struggle against MNS, which attacked north Indians who are also Hindus.
Another fact is, the BJP is supported not by masses but by English speaking middle class people. they speak but not vote when elections come.
Another thing is, as an opposition party, it failed to launch mass struggles against drought, skyrocketing prices, land distribution to the poor, farmers suicide..
Social psychologist Kuppuswamy stated in his book " an introduction to social psychology' that people can be influenced by mantras like food, shelter which are their primary needs.
THIS IS PURELY AN ANALYSIS EMPLOYING THE TOOLS OF SOCIAL PSYCHOLOGY.
