During the 2019 Indian general election, the Bharatiya Janata Party (BJP) chose not to field a candidate in the Mandya Lok Sabha constituency and instead extended support to independent candidate Sumalatha Ambareesh. The decision was aimed at consolidating the anti-government vote against the Congress–JD(S) alliance, whose candidate was Nikhil Kumaraswamy, son of Chief Minister H. D. Kumaraswamy and grandson of former Prime Minister H. D. Deve Gowda. Mandya was regarded as a prestige constituency for the JD(S).

Sumalatha, the widow of Kannada actor and former Congress MP Ambareesh, entered the election as an independent after the Congress allotted the Mandya seat to its alliance partner, the JD(S). Although she met senior BJP leader S. M. Krishna, she chose not to contest on a BJP ticket. Her campaign received support from several leading Kannada film actors, including Yash, Darshan, and Sudeep, while some local Congress workers also backed her despite the alliance.

In the election, Sumalatha Ambareesh defeated Nikhil Kumaraswamy by 125,876 votes. Her victory was considered a major setback for the Congress–JD(S) alliance and a significant political success for the BJP's strategy of supporting an independent candidate without contesting the seat.

United Progressive Alliance

colspan="6" United Progressive Alliance Party Flag Symbol Leader Seats Mallikarjun Kharge 21 H. D. Kumaraswamy 7 Total28 The Congress–Janata Dal (Secular) (JD(S)) alliance contested the 2019 Indian general election in Karnataka as a pre-poll coalition against the Bharatiya Janata Party (BJP). The alliance was formed after the Congress supported the JD(S) in forming the Karnataka government following the 2018 Karnataka Legislative Assembly election. Under the arrangement, H. D. Kumaraswamy served as Chief Minister while the Congress became the junior coalition partner. The two parties announced that they would jointly contest the 2019 Lok Sabha election in an attempt to consolidate anti-BJP votes in the state.

The alliance entered the election with a seat-sharing agreement under which the Congress contested 21 of Karnataka's 28 Lok Sabha constituencies, while the JD(S) contested the remaining 7. A coalition coordination and monitoring committee, chaired by former Chief Minister Siddaramaiah with JD(S) leader Danish Ali as convenor, was created to coordinate governance and election strategy. The alliance expected effective transfer of votes between Congress and JD(S) supporters in constituencies contested by either partner.

During the election campaign, the alliance highlighted its governance record in Karnataka and campaigned jointly against the BJP. However, the coalition remained under strain due to ideological differences, internal factionalism and disagreements over seat-sharing. Several Congress leaders and workers expressed dissatisfaction over constituencies allotted to the JD(S), while reports emerged of local leaders refusing to campaign wholeheartedly for alliance candidates. Prime Minister Narendra Modi repeatedly criticised the coalition, describing it as a "20 per cent commission government" and accusing it of corruption and dynastic politics. BJP leaders also alleged that the coalition government lacked stability.

The alliance suffered a heavy defeat in the election. The BJP won 25 of Karnataka's 28 Lok Sabha seats, while the Congress retained only Bengaluru Rural, where D. K. Suresh was re-elected. The JD(S) retained only Hassan, where Prajwal Revanna won his maiden parliamentary election. Independent candidate Sumalatha Ambareesh, backed by the BJP, won the Mandya constituency.

The alliance's poor performance was widely attributed to ineffective vote transfer between Congress and JD(S) supporters, dissatisfaction among party workers over the seat-sharing arrangement, and continuing internal conflicts within the coalition government. The results led to renewed speculation about the stability of the Congress–JD(S) government in Karnataka, with reports suggesting that disgruntled legislators from both parties could defect to the BJP. The defeat significantly weakened the coalition and marked one of the BJP's strongest electoral performances in Karnataka.

During the 2019 Indian general election in Karnataka, the Indian National Congress allotted the Tumakuru Lok Sabha constituency to its alliance partner, the Janata Dal (Secular), under the seat-sharing agreement. Former Prime Minister H. D. Deve Gowda contested from Tumakuru after vacating his traditional Hassan constituency for his grandson Prajwal Revanna. The decision led to a rebellion by sitting Congress MP S. P. Muddahanumegowda, who filed his nomination as an independent despite party directives to withdraw.

The Janata Dal (Secular) later requested the Congress to contest the Bengaluru North constituency, stating that it was unable to identify a suitable candidate. The Congress subsequently fielded state minister Krishna Byre Gowda against the BJP's sitting MP and Union Minister D. V. Sadananda Gowda. In the election, D. V. Sadananda Gowda retained the seat, defeating Krishna Byre Gowda by 147,518 votes.
