Ideologies have always been notoriously susceptible to political exigencies. And M. Karunanidhi, now in his fourth term as the chief minister of Tamil Nadu, is no exception to that dictum. The 77-year-old leader of the Dravida Munnetra Kazhagam, whos ruled the state for a total of 13 years since 1969, is clearly emerging as a man of contradictions. Be it the case of DMK cadres sporting the religious kumkum on their foreheads or his equivocation on the rss, Karunanidhi seems to be trapped between his own past and the imperatives of state power. His latest utterances on developments in Sri Lanka are yet another indicator of the competitive forces acting within the DMK.
