Few might be aware that BJP opened its account in Tamil Nadu by winning civic polls in Ramanathapuram town in 2011. Currently it has a miniscule 2% vote share in TN but parties such as MDMK and DMDK are looking at it with interest after the response to Narendra Modi's Trichy rally. Support from educated youth, first time voters and middle class is expected to surge for BJP after NaMo's Trichy rally. Rethink among Tamil Nadu parties after Modi rally in Trichy CHENNAI: The huge crowds at Narendra Modi's recent rally in Trichy have triggered minor political tremors in Tamil Nadu. Parties which viewed his visit and the hype around it with skepticism are being forced to reassess their options. Even senior DMK leaders concede that the response to the rally has proved that the Modi factor cannot be discounted in TN . The battlelines may be drawn with DMK moving tentatively closer to the Congress and the AIADMK determined to go it alone with perhaps just the two Left parties for company but the emerging view seems to be that the Modi rally may shape the contours of pre-poll alliances further. Significant among the reactions to the September 26 rally was that of DMK chief M Karunanidhi who since his dalliance with the saffron party between 1999 and 2004, has been a consistent BJP basher. According to a former union minister, Karunanidhi is reported to have said after looking at the TV footage of Modi's public meeting that the party could not afford to "underestimate" the BJP anymore. There are at least nine Lok Sabha constituencies where the Modi factor may force rivals to rethink their strategy. These are constituencies where the BJP may emerge as a serious contender with help from smaller regional parties and where AIADMK and DMK are likely to be wary of a three-sided contest with a BJP-led formation in the fray. For the party - which had a 2% vote share in the last general elections - is expected to see a surge in its core support base comprising the educated middleclass and young and first-time voters in urban constituencies including Chennai, Coimbatore, Trichy and Tiruppur. A chunk of votes are expected to come from the more than 40 lakh first-time voters in TN. BJP's campaign on social media is expected to convert a sizeable section into voters. A VCK leader, who was unwilling to be named, said, "There seems to be a surge among the youth in favour of Modi after his visit to Tamil Nadu." BJP claims that the party's reign in Karnataka has already helped RSS gain a foothold in Tamil Nadu's border areas such as Krishnagiri. Once considered too insignificant for even smaller regional parties to strike a deal, it appears to be gaining supporters in new territories. For starters, MDMK which has small pockets of influence in southern and western TN, has made it known that it is keen on a tie-up with BJP. The saffron brigade is also banking on its surprise win in the 2011 civic polls in Ramanathapuram in the south to see it through in the Lok Sabha elections, according to Thamizhisai Soundarrajan, one of the party's national secretaries from the state. "There were doubts among political parties here as to whether Modiji can be a crowd puller in Tamil Nadu like in the North. The success of the Trichy meeting has changed their perspective," she told TOI. Political observers do not rule out the possibility of the DMK ditching the Congress in favour of the BJP. Tamil Nadu BJP leaders are already debating a dream combination that would include the DMK, the DMDK and itself. They are also optimistic about the ruling AIADMK shedding its reservations and opting for a tie-up with them. Senior leaders point out that the number of votes a tie-up with the BJP may bring against the backdrop of the perceived Modi fervour could far exceed the 3% combined vote share of the CPI and CPM besides some minority support. The DMDK too is assessing the Modi effect and whether it would compensate the loss of minority votes. "The impact of Modi's visit has proved that the BJP is not an untouchable in Tamil Nadu any more," said party's national secretary L Ganesan. "Except for the Congress, the Left parties and the Muslim parties, there are chances of alliances with any party in Tamil Nadu," he said.
