Karnataka's three Deputy CMs: Boon or bane?

Karnataka's three Deputy CMs: Boon or bane?
It has been a day since BS Yediyurappa appointed three deputy chief ministers many days after the Congress-JDS government fell.  
 
Govind Karjol, CN Ashwath Narayan and Laxman Savadi belong to Scheduled Caste, Vokkaliga and Lingayat communities. The appointments have been made as per the instructions of the high command and in keeping with certain electoral compulsions.  
 
Meanwhile, many are shocked that former CM Jagadish Shettar, KS Eshwarappa, B Sriramulu and R Ashoka have been left out. 
 
Needless to say, the CM has tried to avert a political rebellion by appointing not one but three deputies.  However, analysts say that this kind of manoeuvering can work only for a year or two.  Or, maybe, even less than that.  In the long-term, tricks like these can't save a wobbly government.  "It's not clear if the deputies will get any real power.  They may end up being paper tigers," a commentator says.
