Is Shashi Tharoor eligible for ST quota?

Ok, the title is rather provocative and figment of my imagination*. I have lot of respect for Shashi Tharoor. So, it was with some amusement, concern and disgust that I greeted the news of him standing for the Indian parliamentary elections from the south indian city of Thiruvanthapuram. He has snowball's chance in hell in making a mark, leave alone winning the constituency.

Almost all well meaning Indians of reasonable charisma and fame sooner or later decide that the way to "serve" the country is by becoming an elected representative. I thought Dr. Tharoor was smarter to fall for that (Maybe, he went off the rockers when he did not become the UN Secretary General. Or, maybe, the keralite in him caused him to reconnect with Kerala on retirement, just like a lot of Non-resident malayalis (NRM) do). For a man who has lived almost all of his entire adult life outside the country (leave alone Thiruvanthapuram) to think he can connect with the people and can fulfill the role of their representative smacks of naiveté. Dr. Tharoor does a great job of presenting India to Indians and the world from his vantage position of a native looking in from the outside. However, elected representatives need to be insiders looking out. And, no, I don't think they need to be natives.

PS: I don't think just because his initials are ST (scheduled tribe) gives his any advantage. And, the constituency where he is contesting is not a reserved constituency.
