President Elections should happen as it happens in the US or other democracies. First Citizen of the nation cannot be a consensus candidate.
They should have clear Manifesto that should be backed by their credentials.
Today President of India, has too little powers / Role to play. -> He has to hoist flags 5 times during tenure -> Play host to visiting head of states -> Travel to other nations -> Stamping his signature to the bills passed in the parliament.
For this job, Pratibha Patil is as qualified as any of her predecessors.
