IIt is quite a tradition for the Bengali imagination to create catchy limerick-like slogans rhyming native words with English. But the latest one that is flooding social media timelines is going to stick around for a long time – even in its cheery goofiness, it has given rise to an entire zeitgeist, at least within the ruling Trinamool Congress (TMC). “Akasheya batase positive energy / Naam ta mone achhe na: Abhishek Banerjee,” it goes. Yes, the air seems filled with positive energy, and party loyalists owe a lot of it to Mamata Banerjee’s 37-year-old nephew, the anointed successor. Generally cool with the media, he becomes very sharp when he allows himself to speak occasionally, and uses sharp sarcasm when speaking from the opposition benches in the Lok Sabha, where he now faces a young and very audible TMC contingent. He also knows how to keep an aura around himself. The glamor of a scion is not inherited for free, but the aura of hard-earned authority of a man who fought and won in the toxic dust-filled battlefields of Bengal. He says that some of them were also internal to TMC.
