Dear American political consultants: you might think you know how to produce negative political attack ads, but you have much to learn. Caravan magazine’s senior editor Jonathan Shainin on Sunday shared on Twitter what he called “Unquestionably the greatest political poster of all time.” I admit that I have made no broad study, but this ad, coming from Hyderabad in Andhra Pradesh, seems to me to break some kind of sound barrier in the business. (Correction: I cannot confirm that this ad appeared in Hyderabad. A readers whose comment appears below tells  me that the ad appears in Tanuku in West Godavari District)

The Telugu-language ad features a local politician scolding Lok Sabha parliamentarian K Chandrasekhar Rao, a proponent of splitting Andhra Pradesh into two states. Reuters explains why creating a new state, Telangana, is controversial:

The ruling Congress party approved on Tuesday the creation of a new Telangana state, a move that has revived deep political divisions and raised fears of violence in the area, home to global firms including Google.

The decision to break up Andhra Pradesh and establish Telangana comes ahead of elections next year and critics say the ruling party is seeking to shore up its political fortunes after dragging its feet over the explosive issue for four decades.
