Regional parties have some compulsions be it TDP or BSP. Except for Congress and Left there is not a single party who is taking a stand on Nuclear deal. Even BJP is opposing it simply because they don't want to it happen during UPA regime. Mayawati has not other Agenda but to see herself as PM. TDP is only choice in the state is to remain to be on the opposite side of Congress whatever it takes.Same with DMK,PMK,AIADMK,etc.,
