The 2004 Lok Sabha election was held much before the term of Atal Bihari Vajpayee expired because of the mounting pressures from the coalition partners. This was first election of its kind in terms of “a contest at the national level between two serious coalitions, the National Democratic Alliance (NDA) and the United Progressive Alliance (UPA). In this election, the BJP was reduced to second position from its position of single largest party in 1999 election. The present work has been carried out on the electoral performance of the BJP in the 2004 Lok Sabha elections in terms of percent votes, seats won and seats contested by the BJP. An attempt also has been made to find the reasons behind the losses.
