A cyclist passes by a Bahujan Samajwadi Party (BSP) election campaign poster in Aligarh, Uttar Pradesh, India, on Tuesday, Aug. 23, 2016. Prime Minister Narendra Modi's Hindu-nationalist Bharatiya Janata Party (BJP) is seeking to woo Dalits in order to win the state's legislative elections, which would give him greater momentum to push his economic agenda at the national level.
