Well there is no reason to believe that people in Bengal vote for the left parties because they subscribe to their idealogy and slogans. People vote them because the Left parties have deeply rooted bases in every nook and corner of Bengal and they identify each and every house as Left or Other Party very diligently. Now people who wants to run a buidling contracting business or a shop has to vote the left or they are threatened to be killed even. Even doctors, teachers and landlords and even professionals are compelled to vote them or be alienated from the society. It is not so much in the city as it is rampant in the villages. People are Left by birth. Other parties may not be so much organized in this crime in other states and hence they do not succeed to cling onto their 'seats of power' for 30 years. Left knows how to create a vote monopoly and then keep its people illeterate, poor, down trodden and pathetic for several years to come.
