Keeping the specific reference of the author to IITs and IISc, I am personally of the opinion that political parties should not be allowed to make a proxy entry into such campuses in any guise because the very purpose behind the creation of such institutes is likely to be affected by unwanted political interference and influence.
'Knowing others is wisdom, knowing yourself is Enlightenment'- Lao Tzu
What India needs is good leaders who are young and can have a different view about traditional issues. If you look are present-day leaders, the good ones are old and have a few years of political life left.
So, IISc, IITs are the good pool of talent and skill for the country to look forward to future leaders who can take India to a new level. The big 'if' here is if and when these youngsters become influenced by power and corruption which would be counter-productive. The college authorities should have a bigger say in keeping these college elections free from an influence of existing national or fringe parties.
Honesty is the best policy.
