It's the advertising, stupid! That's the ruling dictum as both the bjp-led National Democratic Alliance (nda) and the Congress hunker down over their drawing boards for the coming Lok Sabha elections. And don't be surprised if the conversation in the coming weeks at the bjp and the Congress poll headquarters begin to resemble boardroom strategy sessions in consumer goods manufacturing corporates. Positioning, segmentation, brand image, core benefit: expect to hear these terms if you plan to eavesdrop.
