Congress party Prime ministers Jawaharlal Nehru, Lal Bahadur Shastri and Indira Gandhi. His last position in government was as Deputy Prime Minister of India in the Janata Party government of 1977–1979, In modern times several Bharatiya Janata Party leaders were Dalits, including Dinanath Bhaskar, Ramchandra Veerappa and Suraj Bhan. In India's most populous state, Uttar Pradesh, Dalits have had a major political impact. The Dalit-led Bahujan Samaj Party (BSP) had previously run the government and that party's leader, Mayawati, served several times as chief minister. Regarding her election in 2007, some reports claimed her victory was due to her ability to win support from both 17 per cent of Muslims and nearly 17 per cent Brahmins alongside 80 per cent of Dalits. However, surveys of voters on the eve of elections, indicated that caste loyalties were not the voters' principal concern. Instead, inflation and other issues of social and economic development dictated the outcome. Mayawati's success in reaching across castes has led to speculation about her as a potential future Prime Minister of India. Aside from Mayawati in Uttar Pradesh, Damodaram Sanjivayya was chief minister of Andhra Pradesh from 11 January 1960 to 12 March 1962, and Jitan Ram Manjhi was chief minister of Bihar for just under a year. In 1997, K. R. Narayanan, who was a Dalit, was elected as President of India. In 2017, Ramnath Kovind was elected as the President of India, becoming the second dalit president of the country.

There have been instances where it has been alleged that an election-winning party reneged on promises made to the Dalits made during the election campaign or have excluded them from party affairs.
