What did BJP do during their 5 years?? Can you just point one?? The economic reform (and subsequent growth of our country) was initiated by Mr Manmohan Singh during Rao's govt..
Even the promises, BJP made before election, were not kept. They said, it was because of the coalition dharma. That means, in future, since we are likely to get coalition governments, BJP will never keep their promises, if it comes to power!
