The Karnataka MLC elections delivered a clean sweep for the BJP-led NDA on October 28, 2026. The BJP retained three Legislative Council constituencies, while its ally Janata Dal (Secular) defeated the ruling Congress in Bengaluru Teachers'. Congress failed to win a single seat in the four contests held on October 23.

The outcome is a political setback for the state's governing party, particularly among registered teachers and graduates. However, it does not change the Congress government's majority in the Legislative Assembly or determine how the broader electorate will vote in the next state election.

Karnataka MLC Elections: All Four Winners and Victory Margins

Counting started on October 27. The results for Bengaluru Teachers' and North-East Teachers' were announced that day, while the two graduates' constituencies concluded after overnight counting on October 28, according to PTI's report.

According to The South First's constituency-wise report, Namoshi secured 15,596 votes against Congress candidate Sharanappa Mattur's 12,299. In West Graduates', Sankanur received 33,711 votes against Mohan Limbikai's 24,388. Suresh, the BJP's South-East Graduates' candidate, received 66,020 first-preference votes against Congress nominee Shashi Hulikunte Mutt's 42,922.

Bengaluru Teachers' Seat Delivers the Biggest Political Upset

The most closely watched contest was Bengaluru Teachers', where JD(S) candidate A. P. Ranganath defeated five-time MLC Puttanna, the Congress incumbent, by 908 votes. Ranganath secured 10,810 first-preference votes, compared with Puttanna's 9,902, according to The New Indian Express. The result is particularly significant because Puttanna had switched from JD(S) to Congress ahead of the 2023 Assembly election. He defeated Ranganath in a 2024 by-election, making Tuesday's result a reversal of their previous contest.

The Karnataka MLC elections used paper ballots rather than electronic voting machines, as is the established practice for these constituencies. Eligible registered teachers and graduates vote through separate electoral rolls, making the contests different from a regular Assembly election.

Why Turnout and Alliance Coordination Matter

Turnout was substantial across all four constituencies.

These are specialised electorates in which local networks, candidate relationships and campaigning among educators and graduates can be particularly important.

The result gives the BJP and JD(S) evidence that their seat-sharing arrangement worked successfully in these four races. However, a 4–0 victory does not independently establish how many individual supporters transferred their preferences between the two parties.

The BJP also used the result to mock Congress leader D. K. Shivakumar on social media, posting “DK, it's done, bro!”, according to India Today. The remark reflects the BJP's political response to the result, rather than an independent explanation of why Congress lost.

Does the Result Threaten the Congress Government?

No. Legislative Council elections and Assembly confidence votes are different. Winning four Council seats does not overturn the governing party's majority in the Assembly.

The Karnataka MLC elections nevertheless give the opposition a political boost ahead of future contests, including the scheduled 2028 Assembly election. For Congress, the immediate task is understanding why it lost Bengaluru Teachers' and failed to make gains in the other three constituencies.

For the BJP-JD(S) alliance, the next challenge is demonstrating whether the coordination evident in these specialised electorates can translate into support among the much larger Assembly electorate. The October 28 result is a clear victory for the opposition alliance, but its broader political implications will become clearer in future elections.
