communists win by rigging and forceful means only. Only communists party has full time paid cadres at every corners in Bengal. If there is any opposition, they finish him/her in the dark misusing state law, police. every sector of life in Bengal is policized. Bangals (illegal bangladeshis) are another major reason for CPM in power. Because those illegals need ration card and voter ID to servive in INDIA and therefore they support present ruling party. Congress party in Bengal is B team of CPM. Pranab Mukherjee is most dangerous than CPM, because at the center CPM manage every dirty things they do in Bengal (including Singur, Nandigram). and so on....
