Congress has no fixed, nationalist and common policy.It differs State to State.
So is the case of BJP. Communists too have different policies even in communists ruled States. NCP is again proved to be a regional party.There are no true Nationalist parties in India now. Any Government formed with parties of different idealogies will suffer from cohesion and effectiveness.Our future appears to be very dim.
Solutions are electoral reforms like minimum graduate qualification & police verification of candidates, legalisation of money donated to parties by corporate house, more transperemcy in administration which will reduce corruption & more accountability of IAS Officers many of whom teach these dirty tricks of looting public money to politicians. Have hope all is not lost yet & if people lose patience there may be a revolution also.
