In the 2014 election, the BJP had won 17 seats in the state, while the Congress got nine and the JD-S just two.
Prominent figures in this election included former Prime Minister and JD-S supremo H.D. Deve Gowda.
Nikhil Kumaraswamy, a second grandson, contested from Mandya, a seat traditionally held by the Congress but given to the JD-S in the seat-sharing exercise. He faced off against independent candidate Sumalatha, wife of late actor-turned-politician Ambareesh. She had the support of the BJP as this was the only seat the saffron party did not contest.
For the Congress, leader in the outgoing Lok Sabha and MP from Gulbarga, Mallikarjun Kharge, and state Agriculture Minister Krishna Byre Gowda, were among the prominent faces this election. Gowda contested from Bangalore South against the BJP's union minister Sadananda Gowda.
