Given the number of Indians in the US, I'd say they are grossly under represented in key positions.
Clinton and Obama are not in the least bit influenced by Indians serving their administration - I'd in fact doubt if they see them more than once a year that too perhaps in a XMas party or something
I don't agree with you. Indian command much respect after 911 than counterpart Pakistanis. Now the Indian influence on Americans is enormous. Beleive me. However before 911, status of Pakistanis were a different story. Indian took full advantage of 911 and always quote that incident to down the Pakistnis and Muslims in every walk of life.
