Swamy, Chamundheswari constituentcy after de-limitation has become a vokkaloga dominated constituentcy. If you observe,all 3 canddiates basavegowda,manjegowda and Ashwath narayana are vokkaligas. In 2008 lot of vokkaligas had voted to BJP.but now the political and caste calculattions are changed.Jd(s) has improved its image as well improved the party structure. Thats the reason,there are many contenders for this seat in Jd(s). This is the reason why CN manje gowda who contested last time on BJP seat has joined Jd(s) now.I strongly believe that this seat is going for Jd(s) this time.
