with the kind of public like you, it is not easy to put it across to one billion people in india about the deal. The PM cannot wait for the acceptance from one billion people and then give the acceptance to US. Even Mr Abdul Kalam, the father of India's nuclear program has said that the deal is good for the future of our country, what more do u require to know the benefits of the deal.
Moreover, conducting general elections is not a simple affair, it will cost the exchequer about 1000 crores for an election which i am sure no common, intelligent, broad minded indian would want at this time. And also if elections are held now, it is the UPA which will again come back and not the BJP led NDA.
