Here are some of the famous faces queued up to get ink mark on their fingers.
Sowmiya Anbumani is the president of Pasumai Thayagam, an NGO involved in conservation of nature.
Constituencies that are going to the polls in the first phase, slated for April 19, have just 19 days for campaigning. Contrast that with those going to polls in the 7th phase, notes N Sathiya Moorthy.
Ramachandran, an OPS loyalist who took part in the meeting, said the former chief minister would soon meet VK Sasikala, the confidante of former party supremo J Jayalalithaa.
"Let us all together stop the party and government from going into the hands of a single family again. Let us form a people's government again in sync with the aspirations of people and till then this struggle will continue," he said.
However, in the event of the Bharatiya Janata Party deciding to contest, his candidate would withdraw from the race, he said.
The BJP is now inventing new angles to keep its campaign relevant -- even if it's old wine in an old bottle, which is what the allegation on 'Katchatheevu' is, notes N Sathiya Moorthy.
Wednesday's Vikravandi by-election has become a referendum on the Stalin government, notes N Sathiya Moorthy.
The Erode East assembly by-poll suddenly turned the spotlight on Bharatiya Janata Party with the All India Anna Dravida Munnetra Kazhagam factions led by K Palaniswami and O Panneerselvam rushing to Kamalalayam -- BJP state headquarters in Chennai -- seeking the saffron party's support for their respective parties.
The BJP often forgets that in Dravidian Tamil Nadu, the voter does not mix religion, which is personal, and politics that is in the public sphere, points out N Sathiya Moorthy.
Former Chief Minister Panneerselvam's decision was made in the wake of an appeal by the BJP to put up a common candidate to defeat the DMK backed Congress candidate in the election.
In focus are the assembly polls in 2026. From a BJP perspective, their attack on the ruling DMK, using the 'Hindutva' card, and Annamalai's targeting of both Dravidian majors on corruption has not worked, points out N Sathiya Moorthy.
Clad in black shirts and white dhotis, the AIADMK members gathered in large numbers at the historic Valluvar Kottam in Chennai to stage a fast agitation demanding that Udayakumar be allotted Panneerselvam's chair in the assembly.
Panneerselvam indicated that he would support the move but laid down certain conditions, he said without divulging them. "I hope the two factions would sort out the differences soon," Annamalai said.
'When you weigh anti-incumbency against the Centre against anti-incumbency against the state, anti-incumbency against the Centre will triumph as this is a parliamentary election.'

The deposed coordinator, heading a small faction, hopes to consolidate Amma (late Chief Minister J Jayalalithaa) loyalists to unify the AIADMK factions aiming to coerce another former Chief Minister K Palaniswami, heading the dominant faction, to accept dual leadership in the party.
The supporters of former Chief Minister K Palaniswami are confident of the council recommending the choice of former lawmaker K S Thennarasu, already announced, as they are numerically strong.
Assembly Speaker M Appavu said leaders of the two AIADMK factions submitted him 6 letters, including 4 from Palaniswami, asking for separate seating arrangement in the Assembly for their respective members.
If Tamil Nadu voters preferred the DMK combine, it owed to the Modi-Annamalai combo's ideological battle which often crossed the line of political decency and also challenged 'Tamil pride', argues N Sathiya Moorthy.
Party spokesperson RM Babu Murugavel tweeted a communication from the EC to Palaniswami and said it had "accepted" the amendments to the AIADMK bylaws, the general secretary election and the appointment of new office-bearers.
The opposition AIADMK's discomfiture is likely to work in favour of the ruling DMK-backed Congress candidate.
The court rejected all petitions, including that against the conduct of the party's General Secretary election.
A bench of justices Surya Kant and Dipankar Datta admitted the appeal filed by Ravindhranath against the high court order for hearing and issued notice to P Milany, who filed the petition challenging his election from the Theni constituency.
Is the unusually and unbearably scorching Sun and the general laxity, bordering on laziness, among voters, responsible, asks N Sathiya Moorthy.

The All India Anna Dravida Munnetra Kazhagam general council meeting on Monday revived the general secretary post, and picked Edappadi K Palaniswami as the interim GS.
The Tamil Nadu assembly on Thursday once again unanimously adopted the bill to ban online gambling, weeks after state Governor R N Ravi had returned it to the government for its reconsideration.
All India Anna Dravida Munnetra Kazhagam coordinator O Panneerselvam on Wednesday appeared to have resigned himself to the fact that the odds are stacked against him and his followers, ahead of the June 23 party meeting which is expected to take up the sole leadership question.
Incidentally, Pannerselvam's call for unity also pertained to deposed AIADMK leader VK Sasikala and her nephew TTV Dhinakaran.
The Madras high court on Thursday declared invalid the 2019 election of expelled All India Anna Dravida Munnetra Kaahagam member O P Ravindhranath from Tamil Nadu's Theni constituency.
There is an impression within the Tamil Nadu BJP -- although no one is airing it -- that over-exposure for Narendra Modi over the past months may work against party candidates, as they have triggered a near-continuous social media debate on his achievements and failures, points out N Sathiya Moorthy.
All India Anna Dravida Munnetra Kazhagam (AIADMK) interim general secretary Edappadi K Palaniswami (EPS) and ousted party leader O Panneerselvam on Tuesday moved the Madras high court against the sealing of the party headquarters by the Tamil Nadu government following violence there on July 11.

The order passed by Justice G Jayachandran on Wednesday, in effect held invalid the July 11 GC meeting.
Palaniswami currently helms the party founded by the charismatic M G Ramachandran and nurtured by the redoubtable J Jayalalithaa.
Indications are that the DMK combine will win more seats than the AIADMK and BJP, but is facing a tough fight in about half a dozen from the rest, predicts N Sathiya Moorthy of the electoral contest in Tamil Nadu.
