BJP cheats have been playing all sorts of games : Communal cards, nationalism cards, falsehood, misleading public on almost all issues of national interest, so much so that they kill your cat and balme it on you. Congress's weakest point is that they are not able to match the false propaganda unleashed by the thugs of BJP, which has a whole battery of them. Congress has one or two Manu Singhvi or Margaret Alva etc. They need full time fully charged dedicated persons who can not only rebutt the false propaganda of BJP but also expose them at each and every misdeeds since their inception.
