What about the fast of Baba Ramdev? Is it different from the demand of Anna Hazare?

Baba Ramdev is going on fast unto death on the issue of “Black Money”. Is it not corruption? Anna Hazare had under gone fast for “Lok Pal Bill” to prevent corruption. How is it different from the demand of Baba Ramdev? If the issues are same why Baba Ramdev does issued a new threat for fast unto death? To whom government should respond?
