Last time JD(s) managed to win 50 seats because Kurubas voted solidly for JD(s). Many of the JD(s) MLAs won by wafer thin margins. 1-2% swing in votes this time will have drastic results. Cong Vote bank remains same as 2004 except they have added 8% of Kuruba Votes at the cost of JD(s). BJP also has its Lingayat Brahmin vote bank same as 2004. Only thing that has changed this time is Kurubas going for cong. I dont think SM Krishna can do much to split Vokaliga votes. If he even manages to get 1-2% of vokaliga votes to cong it will be great achievement.
