Well, one has to recognise achievement. So hats off to Lalu Yadav! I always feel that politicians with a mass base and confidence have a potential which given the right direction and support can work wonders. They are much better than the educated acolytes who populate our ministries through the circuitous route of the Rajya Sabha. In fact the significance of the institution itself is unclear to me.
As for the specific case of Lalu, I think even in Bihar he was no better or worse than the CMs before or after him. It was an upper class party (namely RSS & BJP) propaganda happily lapped up by their sympathisers (the section of the English speaking middle class, especially the US based ones). Then the media, which represents the same sections, took it forward and made it sound as if it was the opinion of the nation.
