India’s Prime Minister Narendra Modi suffered a resounding defeat in a key state election on Sunday, indicating his Hindu nationalist party’s political strength may be slipping as the country struggles to contain an unprecedented surge in coronavirus cases. Modi’s Bharatiya Janata Party (BJP) was unable to dislodge West Bengal state’s firebrand chief minister, Mamata Banerjee, after a hard-fought campaign.

His party also failed to win in two southern states, Tamil Nadu and Kerala. But the BJP secured a second term in the northeastern state of Assam and an alliance with regional parties led it to victory in the union territory of Puducherry. Even before the current virus surge, Modi’s party faced stiff challenges in these local legislative elections. Following the disappointing results, Modi stands weakened but faces no threats to staying on as prime minister until his term ends in 2024. “The BJP started running out of steam as the pandemic spread,” political analyst Nilanjan Mukhopadhyay said. “The verdict in West Bengal state will definitely weaken Modi’s position,” he added, but cautioned that the results needed to be studied further to determine how much they were a referendum on the BJP’s handling of COVID-19. In West Bengal, Banerjee’s All India Trinamool Congress picked up 213 seats out of 292, while the BJP secured 77, according to the Election Commission of India. Two went to other parties. Supporters of the All India Trinamool Congress party — many without masks and ignoring social distancing guidelines — held victory celebrations and set off firecrackers in West Bengal after initial results were released.

Public anger for allowing the elections to go forward despite the risk has been directed at both Modi’s government and the Election Commission. Last week, the High Court in Tamil Nadu state slammed the Election Commission for allowing crowded campaigns in the middle of the pandemic. India’s daily new virus cases began rising past 100,000 in late March, and above 300,000 daily new cases on April 21, collapsing India’s tattered health care system. “Your institution is singularly responsible for the second wave of COVID-19. Your officers should be booked on murder charges probably,” the court said. Polly Roy, a professor of virology at the London School of Hygiene and Tropical Medicine, said last week that India’s extremely dense population and the government’s lax rules about election rallies and religious gatherings fueled the outbreak. Experts have also blamed new, more contagious virus variants. Nationwide, death is so omnipresent that burial grounds are running out of space in many cities, and glowing funeral pyres blaze through the night. With the government unable to maintain a steady supply of oxygen to overwhelmed hospitals, desperate relatives plead for oxygen outside or weep in the street for loved ones who died waiting for treatment. On Sunday, India recorded a slight drop in new infections with 392,488, down from a high of 401,993 in the previous 24 hours. It also reported 3,689 additional deaths, bringing the total number of fatalities to 215,542. Experts believe both figures are an undercount. Modi’s party soared in Hindu-dominated regions in central and northern India since he was elected in 2014. The recent local elections were seen as crucial for the party to gain a foothold in three states that have sizeable minority Muslim populations. The Hindu nationalist BJP has for years been accused of stoking religious polarization and discriminating against minorities.

The Congress party, led by Sonia Gandhi, did poorly in the recent elections, failing to capture power from the BJP in Assam or from Communist parties in Kerala.
