NEW DELHI: BS Yeddyurrappa, BJP’s chief ministerial candidate for the Karnataka assembly polls , is having second thoughts over contesting the elections in the state after party's CM pick Prem Kumar Dhumal suffered a shock defeat in the recently-concluded Himachal Pradesh polls.Yeddyurappa’s reassessment comes hardly a couple of months ahead of the elections in the key state and has sent BJP's central leadership in a tizzy.If BSY pulls out of the race, which is quite likely according to sources close to his family, the BJP will have to go to polls without a CM face.Also, since BSY is a key leader from the Lingayat community, which is BJP's major support base in the state, the party will have to face a tricky challenge of not projecting him as its top leader while making him lead the campaign in the entire state.According to sources, the former Karnataka CM and party MP has already shared his thoughts with his close aides and the BJP leadership.Sources say that BSY might campaign across the state, instead of his own bastion, to garner support for the BJP. If the party wins the polls and declares him chief minister, the 75-year old will have six months to get himself elected as an MLC. That would also prevent a bypoll for the Shimoga parliamentary constituency as Lok Sabha polls will follow soon.
