Kochi, May 30 : The Thrikkakara bypoll, which is just hours away, will be nothing less than a popularity test for CPI-M Chief Minister Pinarayi Vijayan and Leader of Opposition V.D Satheesan as they both hail from the same district. As many as 239 polling booths have been set up at the upcountry constituency in the commercial capital of Kochi. Polling will start at 7 a.m on Tuesday and conclude by 6 p.m. The total electorate in the constituency this time is 1,96,805, up from 1,94,113 in the 2021 April Assembly polls which was won by the now-deceased Congress veteran P.T.Thomas with a margin of 14,329 votes. In 2021, 70.36 of the electorate cast their votes. Given the intense campaigning this time, the voting percentage is likely to touch 75 per cent. Thomas's passing away in December last year, necessitated the fresh poll with the Congress fielding his widow Uma Thomas, while the CPI-M brought in a young interventional cardiologist Joe Joseph. The BJP, meanwhile, went for veteran leader A.N.Radhakrishnan. The Left campaign peaked after Vijayan returned from the US after his treatment and since then, around 60 of their legislators were stay put in the constituency as they appear determined to breach the century-mark of legislators in the 140-member Kerala Legislative Assembly. Leading the campaigning by being stay put in the constituency, the Left Democratic Front convenor and CPI-M veteran E.P.Jayarajan expresssed confidence in a swashbuckling win. "Just look at the appalling position of the Congress. It's nowhere to be seen and has lost its might across the country and not to mention in Kerala and Thrikkakara also. We will win hands down, which will see the decimation of the Congress and the UDF here," said Jayarajan. Meanwhile, Satheesan said since this is the first election after he took over and that too happening in his home district, he will be taking the entire responsibility. "We have no doubt of what's in store when the votes will be counted. We expect to increase the margin that we got last time," said Satheesan. The BJP candidate Radhakrishnan said he is seeing is a clear pro-Modi wave and they are expecting a big surprise, similar to what happened in the 2016 Assembly polls when the BJP for the first time opened its account in the Assembly when BJP veteran O.Rajagopal won from the Nemom constituency in capital district. In the 2021 polls, the BJP lost their lone seat. Votes will be counted on Friday. While the Congress expects a minimum margin of 8,000 votes, which might even cross the 20,000, the CPI-M is hopeful of a margin of around 5,000 votes. /IANS
