According to our constitution, the criteria to stand an election in India is only that the candidate must be Indian citizen & the minimum age of the candidate is 25 years. Again our constitution says all the citizen have an equal right to give their vote & stand in the election. According to 2011 census, India's literacy rate is 74%. So if we will tell that our politician should be educated that means rest of 26% people will lose their right to stand in the election.

In India many peoples who are not able to get an education because of their financial reasons. So if they have lost their right to contest an election, they may think that there is no benefit for them to give their vote in the election, where they can't participate.

At last, we can say that Indian literacy rate has increased since our independence for which rise in the number of educated politicians in our country has occurred . So when literacy rate of India is more than 95% like that of countries like US &UK, then automatically all the politicians will be educated. So we should think about our literacy rate rather than the education of our politicians.
