Is Jagan Mohan Reddy Congress' biggest threat today?

Will they, won't they? There is uncertainty over whether the CBI will go ahead and arrest Jagan Reddy after they chargesheeted him and arrested a key financial aide. Jagan is currently campaigning for the crucial by elections in Andhra Pradesh, after 18 MLAs loyal to him quit the Congress. Many feel the arrest could make him a political martyr. Jagan, in his speeches, insists that he is fighting for the people and all charges are because he left the Congress party.
