With hindus voting heavily for BJP, congress attempted appeasement of minorities esp muslims to control the vote bank of minorities. Also, the quota for OBCs was implemented to cement votes from that community. Soon it has realised that its tough to maintain muslims happy. They want gov.t to protect hardcore terrorists, demand special quota, ban nuclear deal, prevent 'alienation' of Kashmir and various other anti national schemes. At this moment UPA is like a 'dhobi ka doggie' and could not get onto either end. 'Best of Bad luck' to this anti national party
