BJP candidate Poonam Mahajan filed her nomination from the Mumbai Northwest constituency today, setting the stage for another showdown with Priya Dutt of the Congress in the Lok Sabha elections. Many have termed the upcoming battle in the constituency as one of political legacies. While Poonam Mahajan is the daughter of the late Pramod Mahajan, who was a senior member in the Atal Bihari Vajpayee cabinet, Priya Dutt is the daughter of late actor-turned-politician Sunil Dutt.
