What will happen to caste calculations?

With the JDS joining hands with the Congress, analysts are busy trying to figure out what will happen to caste calculations.  The former is a party favoured by Vokkaligas, while the latter is not favoured by this important caste group in Karnataka (that's the case at least this election).  

What will happen if this coalition happens?  It might lead to unexpected outcomes, given the nature of the caste-riven electoral realities in the Kannada state.  Psephologist Dr. Praveen Patil says, "Don't know how JDS can go with Congress as there was a massive Vokkaliga consolidation against Siddaramaiah and Congress party. Vokkaligas even went with BJP in a big way to defeat Congress where JDS was not powerful."

Columnist TS Sudhir observes, “A caste consolidation is taking place against Siddaramaiah because of a perception that he is both anti-Vokkaliga and anti-Dalit.”  

In the light of this, is Congress doing the right thing at all? Is BJP secretly enjoying all this drama?
