Hitting back at the Congress for terming the Election Commission a "puppet", the BJP on Thursday said that puppetry is the "art of the Congress" and its attack on the poll body shows their "dynastic arrogance".It said Congress President-elect Rahul Gandhi and his mother Sonia Gandhi had converted "even the office of the Prime Minister into a puppet for 10 years"."Sheer pettiness of Congress to call ECI names is glaring. You loved it when the same ECI declared Ahmed Patel winner in RS polls," tweeted G.V.L Narasimha Rao, National spokesperson, BJP."Why are you taking out your anger now on the ECI for the spontaneous support to the PM? Isn't it too much to expect the ECI to act as Parivar's Darbaris?.""Dynastic arrogance of Nehru dynasty is on vulgar display in its frontal attack on the ECI. How dare you give a notice to King Rahul?."The same mentality evident in PM being called 'neech, tu chai bech' or CEC as a puppet. Request media not to fail in duty and object to such abuse," he added.Attaching a news story with a headline - "Chawla's (former Election Commissioner Navin Chawla) loo breaks led to Congress phone calls: CEC", Rao said: "Does Congress only like such Election Commissioners? Rahul Gandhi, You and Mom converted even the Office of PM into a puppet for 10 years?""Puppetry is your art. Find better excuses for impending defeat. Verbal abuse is no substitute for a massive election defeat," he added.The Congress on Thursday accused the Election Commission of having become a "puppet" in the hands of Prime Minister Narendra Modi, who it said was breaking rules in a last bid to save the BJP's "sinking ship" in Gujarat.
