In westbengal exit poll or opinion poll never matches. Even the big leader expect something and get beyond expectation although they have heavey election machinery. People never disclose the right thing to the media. Mostly voters are in fear and tell in favour of ruling party whatever they have in their mind. This is the situation. This time it is more different thing. Anything can be happens. And TV channels/newspapers are highly polarised I have noticed it. They are not really doing right thing. They are motivated somehow by some political parties.
