The electoral landscape of Paramakudi has been marked by intense competition between the DMK and AIADMK, with the DMK's S. Murugesan emerging victorious in 2021 with 84,864 votes, a significant margin of 13,285 votes over AIADMK's N. Sadhan Prabhakar. However, the DMK's victory in 2021 was a departure from the constituency's historical trend, where the AIADMK has dominated with six victories since the 1977 elections, while the DMK has managed only two wins. This dichotomy raises questions about the factors that have contributed to the AIADMK's long-standing dominance in the constituency.

The 2016 Assembly elections saw AIADMK's Dr. S. Muthiah emerge victorious with 79,254 votes, defeating DMK's U. Thisaiveran by a margin of 13,389 votes. In contrast, the DMK's victory in 2011 was more convincing, with INC's R. Ramprabu being defeated by a margin of 34,606 votes. Thisaiveran's relatively narrow loss in 2016, despite the DMK's strong performance in the state, suggests that the party still has a significant presence in the constituency.

However, the recent performance of the DMK in the constituency has been impressive, with the party's victory in 2021 marking a significant shift in the political dynamics of Paramakudi. This trend is likely to continue in the upcoming Assembly election, where the DMK, led by Chief Minister M K Stalin, will face stiff opposition from the AIADMK and a resurgent BJP-led alliance. The campaign is centred around issues such as welfare schemes, law and order, and the broader debate between Dravidian political identity and national integration narratives.

The DMK's record on industrial growth and social justice has been a major point of contention in the campaign, with the party highlighting its achievements in these areas. However, the opposition has targeted the DMK over allegations of corruption and concerns about power shortages. The AIADMK has also sought to capitalize on the DMK's perceived weaknesses, particularly in the areas of law and order and the economy.

In the midst of this intense competition, the BJP-led alliance has emerged as a significant player in the constituency, with the party's resurgent popularity in the state likely to impact the outcome of the election. The BJP's campaign has focused on issues such as national integration and the party's commitment to good governance, which has resonated with a significant section of the electorate.
