Chief Minister Virabhadra Singh, 83, of the Congress and the BJP's PK Dhumal, 73, lock horns again today as Himachal Pradesh votes for a new government. Polling began at 8 am in the hill state's 68 assembly constituencies. The BJP hopes the state will continue its trend of not voting the same party to power; Virbhadra Singh and PK Dhumal have alternately been Chief Minister for the past 24 years. Results will be announced 40 days later on December 18, along with those for Gujarat, which votes next month.
