In our cacophonic democracy, there are politicians professing many creeds, talking many tongues, pushing many agendas or simply trying to make a little money for themselves.Among them there is also a one-man demolition squad, with no constituency or consistency, always out to get somebody or bring down a government, often successfully. Subramanian Swamy's latest target is the Trivandrum MP, Shashi Tharoor.The former Congress minister was let off mildly for Sunanda Pushkar's sweat equity scandal, while the UPA was in power. Now, Swamy is digging deep into the death of Pushkar and Tharoor's role in the Indian Premier League's alleged behind-the-scenes money laundering and betting syndicates.Simultaneously, Swamy is seeking a CBI enquiry into the change of ownership of Congress' mouthpiece National Herald involving the Gandhis. Both are high voltage cases that can singe the accused if there is any truth in the accusations.Though the Harvard alumnus' cases seem political interest litigations, he was successful in getting A Raja and others prosecuted in the 2G spectrum case and was effective in turning the tide of public opinion against the power-drunk UPA government.In fact, he was part of the grand strategy to expose the Congress-led UPA, which also ensured that BJP becomes a credible national alternative. The first public rally against UPA's corruption was attended by Arvind Kejriwal, Anna Hazare and Swamy among others at the Ram Lila Maidan in Delhi on February 27, 2011. Swamy was also involved in the two-day conference against corruption organized by the Vivekananda International Foundation (VIF), soon after.Along with Sangh Parivar luminaries like S Gurumurthy and KN Govindacharya, Kejriwal too had attended this seminar. Swamy teamed up with Baba Ramdev to launch an offensive against the UPA government over charges of stashing black money abroad.Ram Jethmalani too joined in by moving the Supreme Court seeking the recovery of slush money. The clueless Congress' silence only added credibility to Swamy's repeated accusations against Sonia Gandhi for holding three foreign accounts.The litigations and the public campaigns against UPA's scandals bore fruit. Congress was thoroughly discredited and the UPA bit the dust, making BJP successful and taking Narendra Modi to the South Block, along with a few key functionaries of the VIF such as its director Ajit Doval, who became Modi's National Security Advisor. But 75-year-old Swamy is still in the wilderness, filing cases and writing letters to the Prime Minister.It does not make much political sense for a friendly government to keep Swamy out of power. The last BJP PM who tried that paid heavily. Vajpayee, an old colleague from the Jan Sangh days, knew Swamy too well to let him into his cabinet, though Swamy had brought J Jayalalithaa and the BJP together in 1998.So, Swamy invited Sonia Gandhi and Jayalalithaa for a tea party at The Ashok in April 1999 and got AIADMK to withdraw support to the Vajpayee government, ensuring midterm polls. But, he soon turned against Sonia, accusing her of smuggling out Indian antiques. Then, Swamy only has allies to achieve his short term goals and no long lasting friendships. His recent association with the Sangh Parivar has been steady for the last eight years.After splitting with the Parivar, which promoted Vajpayee and Advani and denied him a cabinet berth in the post-Emergency Janata Party government, Swamy struck a friendship with Chandrashekhar and was his commerce minister in a government propped up by Congress for a few months in 1990-91. Later the Swamy duo, the godman Chandraswamy and Subramnaian Swamy were influential members of Prime Minister Narasimha Rao’s kitchen cabinet.After Vajpayee faded away, Swamy made his re-entry into the Parivar with a book, "Hindus Under Seige" released by the then RSS chief KS Sudarshan in 2006. Now with sponsored posts on Facebook, Swamy is tilting at all anti-Modi windmills, hoping to be useful.
