In the run up to Assembly elections in Karnataka, a war of words has broken out between UP Chief Minister Yogi Adityanath and Karnataka Chief Minister Siddaramaiah. The theme is familiar, but the twist is new. Yogi Adityanath started by telling Mr Siddaramaiah - if you're a true Hindu, then why don't you ban cow slaughter in the state. Mr Siddaramaiah roared back - don't teach me Hindutva, true Hinduism means people can eat what they want. Meanwhile, across the border in BJP-ruled Goa, a very different story. Goa Chief Minister Manohar Parrikar has just defended the legal beef trade in a state where beef is part of the diet of many. This comes even as problems are reported with the supply of beef from Karnataka to Goa, apparently because of vigilante groups. On the Buck Stops Here, we look at the strange dynamics of beef politics. Will it be a decisive factor in the Karnataka elections?
