The campaigning for the first phase of the high-decibel Bihar Assembly Elections will end on Monday evening. The ruling National Democratic Alliance (NDA), comprising, among others, the Bharatiya Janata Party (BJP) and Janata Dal(United), is up against the opposition 'Mahagathbandhan,' comprising the Rashtriya Janata Dal (RJD), Congress and Left parties. Top leaders of both the alliances are making a last-ditch effort to woo the voters as only one day is left for campaigning for the first phase of elections.
