Rap songs have become the new tool for parties to attack each other in Bihar polls. After BJP and JD(U) released campaign songs in Bhojpuri titled ‘Bihar mein ee baa’ (This is in Bihar) to highlight achievements of the Nitish Kumar-led NDA government in the state, the Congress shot back with its own version of ‘ka-ba’ and asking Nitish "Kaa kiye ho”. The party alleged that the state has become a den of corruption under the “corrupt alliance of JD(U) and NDA”.
