Letter to BS: Multiplicity of political parties reduces scope of exit polls

This refers to “A defeat or victory for pollsters?” (February 19) by Atanu Biswas. There are constrains which reduce the appeal and validity of opinion polls in India. With about 900 million voters, much would depend on the reach of pollsters. Second, multiplicity of regional parties together with national parties with their strength varying from state to state complicates the sample design unlike in countries where the fight is between two main parties.
