Shortly after lunch today, dozens of young men and women are busy on the phone at the BJP's headquarters in Shimla, delivering a personal invite to voters in constituencies across north and south Himachal Pradesh, the catchment area for Prime Minister Narendra Modi two rallies in Kangra and Sirmaur on Thursday. "Please do come...," the young volunteer says persuasively. As soon as the call ends, it is time to make another. This is the BJP's war room for the 9 November election to the state's 68 seats; the nerve center of its aggressive campaign to trip Chief Minister Virbhadra Singh, 83, in a state that hasn't returned the ruling party in years.
