This article is nothing more than another media imagination, which projects Bachchan and Narayana Moorthy as presidential candidates while they were never really considered for the job, and has nothing much to do with facts.
Fact of the matter is, President must have very good understanding of the Constitution and political nuances of the country and must understand the pulse of the people. It is best done by a distinguished senior politicain like Pranab Mukherjee. Article even says (on 4th June) Somanath Chatterjee is the front runner! I wish he reads news papers
