Prime Minister Narendra Modi campaigned for his party today in Lucknow with a huge rally at a public park named after the wife of Dalit icon Bhim Rao Ambedkar. The ground was built by Bahujan Samaj Party chief Mayawati when she was Chief Minister; her party says she alone has the drawing power to fill it. "I have never seen such a big audience," said the Prime Minister to a sea of supporters that roared their approval.
