No... in DMK it is money that matters. If Raja can still generate money for the first family in spite of being in Jail then DMK will back him. For coming to power or making money even the brothers and nephews in the family do not mind bringing the family fights to street.. Kani after all is only a mistress's daughter. in DMK support do not get sealed with blood. It gets sealed only with money and political power.

Now DMK main task is to get bail for Kanimozhi at any cost . The party can even dump A Raja for that matter . If Kanimozhi could be freed at the cost of Raja it can also do that . But this stage has not yet come and it has for the time being set its priority for Kanimozhi .
