Unlike opportunistic pre-election pacts, the DMK alliance is anchored by shared ideological principles: defending secularism, protecting linguistic rights, and resisting central encroachment on state financial revenues.

3. TVK's Solo Strategy: High Risk vs. Independent Identity

By choosing not to form pre-poll alliances, TVK aims to project an uncompromised anti-establishment image. However, in Tamil Nadu’s first-past-the-post electoral system, contesting solo without partner vote-transfers leaves candidates vulnerable in tight multi-cornered contests.

4. Vote Split Scenarios Across Multi-Cornered Contests

In constituencies where DMK commands a 40%+ base, even if TVK captures 12% to 15% of opposition votes from AIADMK or neutral voters, DMK candidates remain insulated, maintaining a strong margin of victory.
