More than caste arithmetic, it's the iron-man image of Narendra Modi that can give a huge advantage to the BJP in 2014 if Modi is handed over the mantle to take on Rahul Gandhi. A nation plagued by terrorism, corruption, mass unemployment, poverty, complete absence of basic social infrastructure is desperately looking for a leader who can be decisive and who is not afraid of taking risks. As far as the BJP is concerned, it's only Modi who has got the charisma that runs across the nation . He is the only regional leader who has got national following. The BJP has no other option than to fully encash it if it has to challenge Rahul Gandhi successfully in 2014.
