Do you think that Indian politicians are true to their voters?

India is a democratic country and the largest democracy. Politicians gets elected to the Parliment (Lok Shabha or Rajya Sabha) as an MP from their respective states under a banner of a party. They come to the doorstep of the voters for getting the votes from the consituency they are contesting. After they win the election (majority of the MP"s), they forget the values, ethics, morals and do not do anything to the people and do not listen to the common-man's misery. We the public belive in them and cast our valuable votes in favour of them and end up as sufferers.
