POLITICAL parties in Tamil Nadu are gripped by the old existentialist question—to blow with the wind or bend with the grass. After sending the nation into one of those periodic bouts of suspense, on Saturday the AIADMK leadership again relented on its support to the BJP coalition. Which is not to say that the BJP can rest easy. As AIADMK leader and Union minister K. Janarthanam clarified: "Though we will be participating in Parliament, we will not tone down our demand for the dismissal of the DMK government. There may be walkouts on the basis of issues as they arise."
