Thanks to DMK family politics and its monopoly on TN politics...
UP, a state with 10% bramins, 10% Kshatriyas and 10% Baniyas (30% Forward castes) voted for Mayawathi as the CM in 2006. Dalits make up 20% of UP's population.
In TamilNadu, a state with just 3% bramins, 11% forward castes, 55% OBC-BC-MBCs a Dalit can never become the CM. Why?
Surprisingly ,Dalits make 20% of TN's population. Same as in UP.
See the world of difference between UP and TN and see the DMK's Social justice in a different light... you will know the reality.
