You should vote out these castiest parties like BJP, BSP and Congress. The congress is actually a castiest party as we have been seeing in northern states of India like, Gujarat, Rajasthan, Madhyaprades, Maharashtra, whenever, there is election, they will see each and every parliament/assembly seat, which cast is more, if the muslim minority is more they will put up a muslim candidate and if hindu community voters are more they will put a hindu candidates. This was following since independence and hence the congress is out from the major states like, UP, Bihar, MP, Rajasthan, Madhyapradesh.
