India's largest state, Uttar Pradesh, goes to the polls in February 2012. Uttar Pradesh in the northern region has an estimated population exceeding 200 million. 15% of the parliament seats are from U.P. Uttar Pradesh used to be a major stronghold of the ruling Congress party since independence in 1947 during the Nehru and Indira Gandhi years. More recently in the 2002 and 2007 elections Congress failed to get more than 25 seats out of a total of 219 in this state. The state government is now run by a caste based party called the Bahujan Samajwadi party- which draws its support from Dalits a caste lower placed in the caste hierarchy- led by Kumari Mayawati. The election campaign is also being conducted under new rules designed to limit campaign expenses and limit extravagance in election campaigning.
