The Fragile Fortress, Why the Congress, Not the DMK, Stands to Lose Most If the Tamil Nadu Alliance Frays
At a time when opposition to the BJP has become fragmented or weakened across India, the DMK-led Secular Progressive Alliance (SPA) in Tamil Nadu remains the most robust multi-party anti-BJP formation. Its strength derives from ideological cohesion rooted in the state’s distinct socio-political ethos and the seamless ability of its constituent parties to transfer votes to one another. In a political landscape marked by shifting allegiances and fragile coalitions, the SPA has been a rare bastion of stability.
Yet recent developments threaten to fray this alliance. Second-rung Congress leaders have either critiqued the DMK or demanded a direct share in power, stretching the seams dangerously close to a fallout. MP Manickam Tagore and All India Professionals’ Congress president Praveen Chakravarty have publicly criticised the DMK, even after the high command asked them to refrain from airing such views. The question is why, and more importantly, at what cost?
The Architecture of the Alliance
The arrangement between the SPA’s partners has been clear for over a decade. The DMK forms the government with their support, and the alliance benefits collectively in terms of representation at the Centre, state, and local levels through disciplined vote transfers. This is not a relationship of equals in the sense of shared power, but it is one of mutual benefit. The DMK provides the governmental apparatus; the allies provide the votes that keep the coalition in power and expand its electoral footprint.
For the Congress, this arrangement has been remarkably fruitful. In the 2024 general election, the party reaped a good harvest of MPs from Tamil Nadu precisely because of this alliance arithmetic. The DMK’s organisational machine, combined with the Congress’s own support base in specific constituencies, delivered seats that would have been out of reach for either party contesting alone.
The 2021 state assembly elections tell a similar story. The Congress contested 25 seats and won 18—a strike rate of 72%. In 2016, when the alliance configuration was different, the party contested 41 seats and won only eight, a strike rate of under 20%. The numbers could not be clearer: the Congress performs dramatically better as a junior partner in the DMK-led alliance than it does on its own or in other configurations.
The Demand for Power
The recent critiques from Congress leaders appear to be a bargaining ploy, a signal that the party wants more than just seats to contest. The demand for a “direct share in power” suggests an aspiration to move beyond being a supporting actor to having a role in governance itself.
This is not an unreasonable aspiration in principle. Coalition politics often involves power-sharing arrangements where junior partners receive ministerial positions or other tokens of influence. But in the specific context of Tamil Nadu, such a demand raises practical questions.
Power-sharing would be viable only under certain conditions. One would be if the SPA contested on a jointly drafted common minimum programme, giving the Congress ideological and policy influence even without formal ministerial positions. Another would be if the Congress had substantively increased its support base in the state to a level that necessitated accommodation in government.
Neither condition appears to hold. The Congress’s organisational structure in Tamil Nadu remains moribund. Its support base, while loyal, has not expanded dramatically. The party’s electoral success has come from alliance arithmetic, not from independent mobilisation. And its critiques of the DMK have been opportunistic and ad hoc, surfacing only after actor Vijay’s Tamilaga Vettri Kazhagam (TVK) has emerged as an oppositional force that might offer an alternative alliance partner.
The TVK Temptation
The emergence of the TVK as a political force introduces a new variable into Tamil Nadu’s complex electoral mathematics. Vijay, a popular actor with a massive fan following, has demonstrated an ability to draw crowds and generate enthusiasm. For a party like the Congress, which has struggled to expand its base, the temptation to explore an alliance with a fresh, dynamic force is understandable.
But temptation is not strategy. The TVK is untested and enigmatic. It has no track record of electoral performance, no established organisational network, no proven ability to transfer votes. An alliance with the TVK would be a leap into the unknown.
Moreover, such a move would come at the cost of sacrificing a crucial INDIA bloc ally that delivered the Congress its highest state tally in 2024. The DMK-led alliance is not just any coalition; it is the most robust anti-BJP formation in the country. Walking away from it for the uncertain prospect of a new alliance would be, in the words of the analysis, “pound-foolish and not even penny-wise.”
Who Loses Most?
If the Congress abandons the SPA, it would stand to lose the most. The arithmetic is straightforward. A Congress exit from the SPA would tighten the contest by narrowing the gap between the DMK and the AIADMK (in alliance with the BJP). But the Congress itself would be the biggest casualty.
Many traditional Congress voters, principally opposed to the BJP, are unlikely to follow the party into an alliance with an untested force like the TVK. Their primary political commitment is to keeping the BJP out of power in Tamil Nadu. If the Congress aligns itself with a party that weakens the anti-BJP coalition, those voters will gravitate toward the DMK-led alliance, not toward the Congress.
The Congress would find itself isolated, with a diminished support base and no reliable partner. Its strike rate, which soared to 72% in 2021 under the SPA umbrella, would plummet. Its representation in Parliament and the state assembly would shrink. Its relevance in Tamil Nadu politics would erode further.
The Real Task
The analysis suggests that the Congress leadership would do better focusing on alliance cohesion and working toward resuscitating its moribund organisational structure, rather than rocking the boat in Tamil Nadu. This is sound advice.
Alliance cohesion requires trust, communication, and a shared understanding of mutual benefit. The DMK has demonstrated its reliability as an alliance partner over more than a decade. It has delivered seats, transferred votes, and provided the Congress with a platform it could not build on its own. The quid pro quo has been clear and consistent.
What the Congress needs is not a new alliance but a stronger organisation. It needs to rebuild its grassroots presence, cultivate local leadership, and expand its support base in areas where it is weak. These are long-term tasks, not quick fixes. But they are essential if the party wants to move from being a dependent partner to a more equal player in Tamil Nadu politics.
The Left and VCK Model
The analysis notes that parties like the VCK and the Left have managed to hold the DMK-led government to account on issues of labour and caste discrimination despite being outside the government. They have maintained their ideological distinctiveness while supporting the coalition. They have criticised when necessary and cooperated when possible.
This model offers a path for the Congress. It does not need ministerial positions to have influence. It can articulate its positions, advocate for its policies, and hold the government accountable while remaining a loyal ally. It can build its profile and expand its support base through principled stands, not through public spats with its partner.
Conclusion: The High Cost of Folly
The DMK-led SPA is a rare asset in India’s fragmented opposition landscape. It is robust, cohesive, and electorally effective. The Congress has been a significant beneficiary of this arrangement, winning seats and influence far beyond what its independent strength would warrant.
To jeopardise this alliance for the uncertain prospect of a new partnership with an untested force would be a strategic blunder of the highest order. The Congress would not just lose seats; it would lose relevance. It would demonstrate that it has learned nothing from decades of alliance politics. And it would hand the BJP a gift by weakening the most effective anti-BMP coalition in the country.
The choice is clear. The Congress can continue to benefit from the SPA, focusing on rebuilding its organisation and expanding its base. Or it can chase a mirage and end up stranded in the desert. The consequences of the latter would fall most heavily on the Congress itself.
Q&A: Unpacking the Tamil Nadu Alliance Dynamics
Q1: What makes the DMK-led Secular Progressive Alliance (SPA) unique among anti-BJP coalitions in India?
The SPA is unique because of its ideological cohesion, rooted in Tamil Nadu’s distinct socio-political ethos of Dravidian politics and social justice. Unlike many other opposition alliances that are purely electoral arrangements between parties with conflicting ideologies, the SPA’s constituent parties share broad agreement on core principles. This cohesion enables seamless vote transfers, making the alliance electorally formidable. At a time when opposition to the BJP is fragmented elsewhere, the SPA remains robust and effective.
Q2: How has the Congress benefited from its alliance with the DMK?
The Congress has benefited significantly. In the 2024 general election, it won a substantial number of MPs from Tamil Nadu because of the alliance. In the 2021 state assembly elections, the Congress contested 25 seats and won 18—a 72% strike rate. In 2016, when the alliance configuration was different, it contested 41 seats and won only eight. The numbers demonstrate that the Congress performs dramatically better as a junior partner in the DMK-led alliance than it does on its own.
Q3: Why are some Congress leaders now demanding a share in power, and what are the risks?
The demands appear to be a bargaining ploy, possibly aimed at contesting more assembly seats or gaining ministerial positions. However, the timing coincides with the emergence of actor Vijay’s Tamilaga Vettri Kazhagam (TVK) as a potential alternative ally. The risks are substantial. If the Congress abandons the SPA for an untested TVK alliance, it would sacrifice a proven partnership for an unknown quantity. Traditional Congress voters, opposed to the BJP, are likely to gravitate toward the DMK-led alliance rather than follow the Congress into a new, uncertain alignment.
Q4: What conditions would make power-sharing viable for the Congress in Tamil Nadu?
Power-sharing would be viable under two conditions. First, if the SPA contested on a jointly drafted common minimum programme, giving the Congress ideological and policy influence even without formal ministerial positions. Second, if the Congress had substantively increased its support base in the state to a level that necessitated accommodation in government. Neither condition currently holds. The Congress’s organisational structure remains weak, and its electoral success has come from alliance arithmetic, not independent mobilisation.
Q5: What should the Congress do to strengthen its position in Tamil Nadu?
The analysis suggests two priorities. First, maintain alliance cohesion with the DMK, recognising the proven benefits of the partnership. Second, focus on resuscitating its moribund organisational structure—rebuilding grassroots presence, cultivating local leadership, and expanding its support base in areas where it is weak. Following the model of parties like the VCK and the Left, which hold the government accountable on issues while remaining allies, the Congress can build its profile and influence without jeopardising the alliance.
