In Tamil Nadu’s votes-for-cash industry, R.K. Nagar serves as the best address. Its 2.19 lakh voters had almost a windfall last April during the run-up to the bypoll to the seat in North Chennai that chief minister J. Jayalalitha had occupied. But the Election Commission (EC) stopped the race, citing the huge play of money and a possible match-fixing. Now that the EC has fixed December 21 for electing its MLA, RK Nagar is bustling with political activity and eager expectations.
