Mayawati said she had been travelling to many parts of the state but found "very little" support for Modi. She was interacting with reporters after casting her vote in the state capital.
The former Uttar Pradesh chief minister slammed yoga guru Baba Ramdev for his remarks on Dalit women and questioned the silence of Bharatiya Janata Party (BJP) leaders including Modi on the issue.
"The BJP is making serious efforts to dent the Dalit vote bank, their leaders are visiting Dalit homes and Modi misses no chance to talk about them.
"But there has been no statement slamming the yoga guru," the Bahujan Samaj Party (BSP) chief said.
Mayawati also criticized the Congress leadership, specially its president Sonia Gandhi and vice president Rahul Gandhi, for not saying a word on the remarks made by Ramdev.
"While the BJP is getting support from Ramdev, one can understand its silence. But why is the Congress mum over Ramdev's statement though its yuvraj (Rahul Gandhi) was the centre of the caustic remark?" she asked.
