DMK holds vote share in Tamil Nadu bypolls despite losing Madurantakam, Dharapuram
Synopsis
The DMK lost both Tamil Nadu bypolls to TVK, yet its vote share barely moved — dropping just over 1 percentage point in Madurantakam and under half a point in Dharapuram. That near-flat performance came after Congress, VCK, MDMK, CPI(M), CPI, and IUML all walked out of the DMK alliance, making the core vote hold a signal worth watching ahead of the 2026 state election.
Key Takeaways
DMK lost both Madurantakam and Dharapuram Assembly bypolls to TVK on 10 October 2026 .
Vote share declined by just 1.03 percentage points in Madurantakam and 0.42 percentage points in Dharapuram.
Congress , VCK , MDMK , CPI(M) , CPI , and IUML had all withdrawn from the DMK-led alliance before the bypolls.
DMK improved its finishing position in Madurantakam — from third in the general election to second in the bypoll.
Stalin called the outcome 'a victory within the DMK's defeat' and 'a defeat within TVK's victory.' TVK winners Maragatham Kumaravel and Sathyabama had originally won both seats as AIADMK candidates.
The Dravida Munnetra Kazhagam (DMK) finished second in both the Madurantakam and Dharapuram Assembly bypolls on 10 October 2026, losing to the ruling Tamilaga Vettri Kazhagam (TVK) but holding its vote share with remarkable resilience — despite contesting with a significantly depleted alliance.
Key Developments
The DMK's vote share declined by just 1.03 percentage points in Madurantakam — from 30.18% in the general election to 29.15% — while in Dharapuram the dip was an even narrower 0.42 percentage points, falling from 32.20% to 31.78%. Notably, the party actually improved its standing in Madurantakam, moving from a third-place finish in the general election five months ago to a second-place finish in the bypoll.
In Madurantakam, bypoll candidate I. Paranthaman polled a 29.15% share, compared to general election candidate Amulu Ponmalar's 59,838 votes and 30.18% share. In Dharapuram, bypoll candidate Sukanya secured 57,370 votes and 31.78%, against the general election performance of Indrani, who had polled 64,373 votes at 32.20%.
What the Alliance Erosion Looked Like
The bypolls came after a notable fracture in the DMK-led coalition. The Congress, Viduthalai Chiruthaigal Katchi (VCK), MDMK, CPI(M), CPI, and the Indian Union Muslim League (IUML) all withdrew from the alliance ahead of the contests. The DMK entered both seats backed only by the Manithaneya Jananayaga Katchi and the Manithaneya Makkal Katchi — a substantially narrowed support base compared to general election conditions.
This context makes the party's near-flat vote share all the more significant. Analysts had widely expected a steeper decline given the scale of the alliance collapse.
TVK's Win, the AIADMK's Position
Both seats were won by Maragatham Kumaravel in Madurantakam and Sathyabama in Dharapuram — both of whom had originally won the general election as AIADMK candidates under the 'Two Leaves' symbol, and who now secured fresh mandates as TVK candidates contesting on the 'Whistle' symbol. While the contests formally featured five-way battles, the principal three-way fight was between TVK, DMK, and AIADMK.
What the DMK Said
DMK president M.K. Stalin, speaking to reporters at Kodambakkam in Chennai, framed the result as 'a victory within the DMK's defeat' and 'a defeat within TVK's victory.' His remarks sought to recast a dual loss as a consolidation signal — arguing that the near-stable vote share, achieved without several major allies, demonstrates the DMK's core electoral durability.
The party also drew support through postal ballots: its candidates received 358 of 864 postal votes in Madurantakam and 613 of 1,316 postal votes in Dharapuram.
What Comes Next
The results will be closely read ahead of the Tamil Nadu Assembly elections due in 2026, with all three parties — TVK, DMK, and AIADMK — drawing their own strategic lessons. For DMK, the immediate task is rebuilding or renegotiating alliance structures, particularly with parties like Congress and VCK whose support could prove decisive in a full general election. TVK, meanwhile, has demonstrated incumbent conversion capability, turning two opposition seats into its own column.
Point of View
But Stalin's 'victory within defeat' framing should not obscure the structural problem: the party lost both seats while its principal allies sat out. A near-stable share with a hollowed-out alliance may simply mean the DMK's ceiling is lower than its floor — it is not losing voters, but it is also not gaining them. The real test comes when these allies are courted back for 2026, and whether the price of their return is worth paying.
