Ever since voters have been provided the ‘None of the Above’ (NOTA) option if they do not want to vote for any of the candidates in the fray, political parties now cite many voters having chosen NOTA as a reason for losing an election.

But overall, there has hardly been any election in India where NOTA has been instrumental in altering an electoral verdict.
