DNA seems to be the hottest buzzword in Bihar ahead of the state Assembly polls. First, Prime Minister Narendra Modi, while attacking Nitish Kumar at a rally in Muzaffarpur on July 25, said there was "some problem with (Chief Minister) Nitish Kumar's DNA", referring to his frequent change of political allegiance. Kumar took umbrage and described the remark as an "insult" to the people of Bihar and decided to send the PM DNA samples of the state's electorate. Now, Jharkhand Chief Minister Raghubar Das has thrown his hat into the ring and alleged at a press conference last week that the "DNA" of the pre-poll alliance of the Janata Dal (United), Rashtriya Janata Dal and Congress is "dhoka (deceit), nautanki (drama) and ahankar (arrogance)".
