Well, Pradeep. People have divergent views and that is perfectly OK in democracy. With all due respect to PC (he certainly has to manage an economy which has sort of "gone out of hands" due to uneven/non-uniform and near-explosive growth) and MS (not easy to be a puppet PM either, especially with the kind of reputation he has reg. his gentleman nature and for steadying the economy in the past), it's an open secret that what Indian economy today has nothing to do with the CURRENT tenure of PC and MS. In fact the current government is exploiting the inherent growth in the economy by incessantly taxing the "guinea pigs" that is the salaried class. Leaving the BJP apart, Congress is well known for their corrupt nature (in all meanings of the term). Just look at the presidential election, the current "hot news". Congress has ALWAYS ensured the presence of "a political" person as president (and state governors) while the constitution clearly specifies "APOLITICAL" persons. You might have your own justifications for hating BJP, but that should not be your justification for LOVING congress for achievements that they do not own.
