I donot agree with the reasons given in the article. As I understand one of the major reason is that most of Nehru clan are highly mediocre ecept Menka who is self made. They are charismatic if they are not exposed to public life. For example Indira ji won 1969 election but was forced to declare emergency and lost badly in 1977,won 1980 but her position was quite bad in 1984. Rajiv won 1985 but could not hold his charishma and exposed his capabilities and lost in 1989. Sonia could not win 1996, 1999 election for congress and brought cong to a state where it is contesting only 4 seats in Bihar.
Sonia does not want to loose control of Nehru family in Indian politics. If all three appear before Indian Public together and their capabilities are known then their hold will be very shortlived. Hence they will appear one by one.
I am deeply overwhelmed to realise the situation. Grate, Nothing is too late, and every one is answerable to the ONE above when time comes to a question. It is surprising to notice the unkindness of a few of our country people, of-course, it is finally the real patriatism will decide who would be what? what worst can happen, other than already happened? Go a head there is always some ONE who can take care, if one delights in Him. May GOD bless you,
