The Congress has shot itself twice in the foot in Tamil Nadu. First, the suspenseful wait before Karti Chidambaram was cleared as the last of its nine candidates from the state for this summer’s parliamentary polls. Such delays are symptomatic, brushed aside and forgotten in the hurly-burly. But not having a single candidate from the religious minorities on its Tamil Nadu list won’t be easily forgiven. That’s the second gaffe; and a big one as the state has a minority population of 18 per cent, almost equally divided between Muslims and Christians.
