What is the BJP strategy?

BJP vice-president Khandelwal calls his party's strategy "perfect management."

"We are never bureaucratic in our approach to the party's affairs in each state. We announced the entire list of candidates in each state much before the election because of the ideal management in each state," Khandelwal told rediff.com

In the BJP, there is an apex committee comprising Prime Minister Atal Bihari Vajpayee, Deputy PM L K Advani, party president M Venkaiah Naidu and senior leaders like Pramod Mahajan to clear nominations.

Khandelwal says the BJP has divided each state into different zones. "For instance, Uttar Pradesh has been divided into six zones: Western, Braj, Kanpore, Awadh, Gorakhpur and Kashi," he explained.

BJP leaders call it micro-level management of political affairs.

What is the Congress strategy?

Congress Working Committee member Ramesh Chennithala claims his party has the most democratic set-up as far as elections are concerned.

"We take care of each state meticulously. Senior leaders are in charge of various states. Problems and candidates in each state are sorted out with precision," Chennithala told rediff.com

The Congress leadership depends on its state units to decide on the right candidates. But factional fights have often compelled the high command to declare candidates without the consent of state leaders.
