Voters will be casting their franchise across 3,197 polling stations in the three constituencies. The votes will be counted on May 2. The Election Commission (EC) has decided to keep polling open for more hours, from 7 a.m. to 7 p.m., to facilitate the compliance of Covid safety rules. The last hour is reserved for Covid positive patients. Ahead of the polling began, both BJP and Congress appealed voters to vote in their respective candidates favour on their Twitter and other social media channels. They also appealed voters to follow Covid safety protocols. By-polls in Belagavi Lok Sabha seat and Basavakalyan assembly seat were necessitated due to Suresh Angadi, a four-time Lok Sabha member from the state's northwest region, died of Covid on September 23, 2020 in New Delhi, while B. Narayan Rao also died of Covid on September 24, 2020 in Bengaluru. But by-polls to Maski assembly constituency is being held due to the disqualification of MLA Prathapagouda Patil, who shifted to the Bharatiya Janata Party (BJP) after winning on a Congress ticket in 2018. The Opposition Congress has tried to corner the ruling BJP over lack of good administration, Karnataka's Covid-19 situation and issues related to reservation of different communities. Even though Sleaze CD case involving former Karnataka minister, Ramesh Jarakiholi did make big news across the state ahead of by-polls in Karnataka, but Congress could not make this as a major a poll plank because it has fielded his younger brother and party's working president Satish Jarakiholi in Belgaum Lok Sabha seat. Congress had won the Basavakalyan and Maski assembly constituencies in 2018 and hopes to retain it in this by-polls. The ruling BJP has fielded Mangala Suresh Angadi, widow of Suresh Angadi for the Belgaum Lok Sabha seat. In Basavakalyan, Congress has fielded Mallamma, the widow of legislator B. Narayan Rao, against the BJP's leader Sharanu Salagar. Mallikarjun Khuba, a rebel leader formerly of the BJP, who is contesting as an Independent candidate is also in the fray. Janata Dal (Secular) which has limited itself to the Basavakalyan assembly constituency in this by-polls has fielded Syed Yasrab Ali Quadri. The BJP has nominated Prathapagouda Patil in Maski, who emerged winner in 2018 against Congress' Basanagouda Turvihal. Turvihal fought on a BJP ticket in 2018 and lost by a thin margin of 213 against Patil who was with the Congress at that time /IANS
