With the BJP decided on backing Vice-President Bhairon Singh Shekhawat as the next man in Rashtrapati Bhavan and sending clear signals that it was ready to lobby across party lines for his candidature against the UPA’s nominee, Trinamool Congress leader Mamata Banerjee today took an NDA meeting by surprise when she suggested that former Prime Minister Atal Behari Vajpayee be fielded for the highest office. The NDA meeting broke up without taking a final call but an analysis by The Indian Express of the electoral college strength of the UPA and NDA (see chart) shows that the BSP and SP, key contestants in UP, also hold the key to who eventually makes it to Rashtrapati Bhavan. The UPA strength is 5.2 lakh votes while the NDA has 4.6 lakh votes. The BSP with 61,000 plus votes and SP with another nearly 60,000 votes hold the key. At the NDA meeting at Vajpayee’s residence, sources said Mamata Banerjee first suggested that President Kalam be asked to run for a second term. When BJP leaders pointed out that he was not prepared to contest, she said they could all go to him and persuade him. The BJP leaders then said that the President would not like to be in a situation where he becomes the Opposition’s candidate. It was then that Banerjee, sources said, came up with Vajpayee’s name. “Who can be better than him?” she is said to have asked the meeting. She even said that he’s “an institution” and all would agree on his name for President.
