Where is the representation?

As an outsider with roots in Andhra, I felt this strong sense of caste in every relative and friend from Andhra. But this post is not about casteism. It's about political representation. Yea, there's reservation in political representation and all, but at the end of the day, it's the upper caste leaders that strongly talk about the rights and reservations of the lower castes. Where are the strong leaders from castes other than those in OC? Not to mention the strong support TDP has among OBCs in Telangana, (I live in warangal and people still talk alot about CBN, despite the party not winning any seat in the region for the last 20 years.) Its seems completely opposite in Andhra. I'm not saying that a particular section of population doesn't support TDP in Andhra, I'm saying. Where are those tall OBC leaders?
