Influencing voters is the crux of all poll campaigns.
Opinion polls often suffer on account of unexpected developments once the electoral process starts, such as the death of a political leader (as in the case of the late Rajiv Gandhi).
Opinion polls sponsored by newspapers were traditionally meant to bring to the fore the mood of the people objectively.
The issue of coverage of pre-poll surveys should not be mixed with the freedom of press. Having guidelines does not violate any fundamental right nor implies any restriction on this freedom. 'Media power' should not be misused with the help of pre-poll surveys.
Elections, in India, are 'over to the people' time. And it is probably the one time in their lives when politicians, and political parties, of all hues walk the razor edge of panic.
Pre-poll surveys receive different reaction in the media among voters and political parties. For example, the more undecided voters are, the greater the role and effect of pre-poll surveys. Similarly, greater the decline of the party system, the more influential their role.
