The Election Commission may have put the brakes on the Congress's Madhya Pradesh by-polls plans by dropping Kamal Nath from the party's "star campaigner" list, but there is a bigger and more interesting story brewing behind the poll body's reprimand of the former Chief Minister. Many feel the focus of these by-polls will be the contribution of the BJP's Jyotiraditya Scindia - the former Congress leader whose controversial cross-over (with that of 22 MLAs) in March triggered the fall of the Kamal Nath government and paved the way for the return of Shivraj Singh Chouhan as Chief Minister.
