may be it wont work for him now... but who knows... please dont put a bad name because one guy is bad.... TN and chennai are by far very neat communities. Sparing a few people like Karunanidhi, Thirumavalavan, Krishanaswamy pudhiya tamilagam, ram gopalan (cant understand why he is so intent on going via triplicane and create confusion), ramadoss - bemaani, and the whole of congress.
Before all these people came - we never used to differentiate communities..infact even JJ doesnt create any issues between hindu muslims like what karunanidhi does... selfish bugger he is.
