Well the report if true suggests that BJP is preparing its cadres to face the inevitible. Arun Jaitley while critising exit polls gave the Punjab example where Amarinder Singh of the Congress was projected as having the edge by exit polls only to be embrassed that the BJP-Akali coasted to almost a comfortable win. The Punjab result is in line to what happened in 2004 Lok sabha elections or UP elections. Opinion and exit polls tend to favor the ruling party. The CNN-IBN exit poll for Gujurat offered the caveat that there was substantial over-reporting (17%) and though they factored this into their vote and seat share projections, they weren't sure whether this was adequate. Perhaps this caused anxiety within BJP about the Gujurat outcome.
