A majority of the MPs and MLAs who will vote in next week's presidential polls are crorepatis, accounting for 75 per cent of the total votes, says a report.
Karunanidhi has been keeping unwell since December last.
Naidu was the first to cast his vote followed by Kodela at the polling booth in the state Assembly's committee hall. Then the special pens with violet ink will be given to the elector for marking the ballots, which would be in two colours - green for MPs and pink for MLAs.
The special pens are being used for the first time in the presidential election, in which National Democratic Alliance's Ram Nath Kovind will compete against United Progressive Alliance's Meira Kumar. Taking the other way round, Bihar Chief Minister and Janata Dal United (JD-U) chief, Nitish Kumar has chose to back Ram Nath Kovind, leaving the opposition twisted. Apart from them, one MLA from Kerala, Abdullah has got special permission from the EC to cast his vote here.
Counting of the votes will be held on Thursday.
MLAs from different states have different vote values depending on the population of the state.
Post the oath taking ceremony which will be taking place on July 25th in the presence of Chief Justice of India (CJI) the new President will be taking over the post.
Once the voting process is over, the ballot boxes will be taken to Delhi under tight security.
The MP Assembly has a total strength of 230 members, but the electoral list for today included 228 MLAs. The AIADMK has 135 MLAs (including the Speaker) in the Assembly. So, 98 MLAs belonging to the DMK and its allies will vote for Meira Kumar. The pens have been introduced following a controversy during voting in the Rajya Sabha polls in Haryana in September 2016.
Meanwhile, at the neighbouring Puducherry all 30 elected legislators who are members of the Electoral College exercised their franchise.
Although the opposition AINRC has eight legislators in the House, one of its members P R N Tirumurugan representing Karaikal, however, turned up at the booth separately and after casting his vote he left the venue without talking to media.
Earlier, Madhya Pradesh Chief Minister Shivraj Singh Chouhan and Leader of Opposition Ajay Singh were among the early voters.
