BJP leader CR Kesavan reacted to Congress chief Mallikarjun Kharge's advice to party's state units that they should make only those promises that are fiscally doable. "[Congress governments] blindly follow...absurd 'khata khat' voodoo economics of Rahul Gandhi," Kesavan said. Kharge's remarks came after Karnataka Deputy CM DK Shivakumar said state government would review one of its poll promises.
