Congress ruled for most of the years in India. When I say rule, it means like kings their family kith and kins automatically inherit the top post. They have neglected the top brain because the first Congress family is itself not very educated. Indira Gandhi was a matric, Rajiv Gandhi, Rahul Gandhi and Priyanka are inter and above all Sonia is not even matriculate. Under them there were innumerable riots, but the party was fortunate as the media then was not 24 x 7. BJP ruled the country with ease and congress brought in twice the no-confidence motion but failed. Sonia has not rejected Prime Minister post, but she knows that there will be a blood bath if she sits on the top post and then nobody will be able to save her family. She is very ordinary like anyone. Obviously, for congressmen she is a tool to attain success.
Congress is breathing its last so the party has come down to its worst like reservations. But by showing her interest in reservations, the party has become eyesore of upper castes.
