You are from North Karnataka. That is the reason you are having the difficulty to understand this. In Mysore - Mandya region there is a strong vokkaliga presence. Livelyhood is agriculture. This is the place which votes for JD-S. Only Deve gowda is proven as a leader for this community. No one else is present in this region who has the calibre of Gowda. Only people who read news papers (read English) hate Gowda(s) and JD-S. These guys have the knowledge of day to day affairs and seen progress in some way. For people of Gowda rajya there is no dream and no development vision. So they continue to vote for the politician from their own cast. When you have to decide between the two evils you will select the one which has some similarity with you.
