The biggest problem with Indiann nationalists is they can't appeal to mass population except few brahmin or thakur casts.
Congress though totally unworthy has managed to appeal the mass population for 60 years at the same time keeping India divided and directionless.
My perosnal opinion is BJP RSS must understand the sentiments of other casts, give up typical brahmin arrogance/image, unite all casts and tribals in our land. Then there will be no need for Congress, sonia and Left anymore.
