Who will take blame for Congress loss if not the party chief? Rahul Gandhi's resignation is classic example of fake humility

Rahul Gandhi's "resignation letter" had me in splits. Don't get me wrong, I am not being frivolous. I am sure having decided to step down as Congress president, Rahul must have written it in all seriousness (assuming he wrote it himself). The gravitas and pathos must be genuine and the comedy purely unintentional.
