during 50 yrs congress built socialistic institutions in the country which were the foundation of research in space,science,agriculture and other things. when the appropriate time came, they liberalised the economy. i admit though that they were late by some years in doing so but thats just a small discrepancy in the wider context. care to tell me what exactly the BJP did all the while other than making noise???? heck they were not even part of india's freedom struggle and their parivar people RSS shot down the father of the nation who gave us freedom. yeah great achievement of BJP!!!!!
