Sonia Gandhi is not imposing the leadership on herself. The partymen imposes on herself. Ask your conscince whether the congress' internal support for Sonia is anything less than 95%. Then why do you speak about internal party democracy. By the bye, what is democracy.
In US the support is more or less same for both Obama and Clinton; the show down which we witnessed couple of weeks back was a ncessity in real sense. Is it required for Sonia when more than 95% of the congressmen support her. Calling congress party one lacking internal democracy is a misnomer. I appreciate the role Sonia Gandhi plays in Indian politics. She has installed the most qualified PM of the world. She is up for eliminating poverty and developing the knowledge sector. In no govt you can see such a rare balance.
There are problems w.r.t reservation, the way they handle the administration of higher education institutions.
But the overall effect is much better than BJP or Coomunists.
