BJP has always been open to insults. The sole reason - lust for power!
Remember how Jayalalita treated them like a door-mat? The so-called towering leaders of BJP assembled at the fax machine for days and when finally the fax arrived, they sang, "Chitth ayi hai, ayi hai.....".
BJP took pride in splitting BSP & Congress in UP to pull down Mayawati's govt. BJP's speaker made a mockery of the anti-defection law. In return, Mayawati pulled the rug down Vajpayee's feet in Delhi.
Uma Bharati insulted Advani in front of TV cameras but was taken back into BJP because of her hold in MP.
We have not forgotten how Advani was hounded & scorned by RSS on Jinnha episode. But the fellow stuck to his post like a leech.
BJP is party of such characters that can take anything for power. The distinguishing feature of BJP is born arrogance, shameless lust for power.
In Karnataka, nothing different will be seen. BJP will make big noise as usual, but will NEVER dare to withdraw support.
