Prashant Kishor, Mamata Banerjee's election strategist for the Bengal polls, appears to say that Prime Minister Narendra Modi is "as popular as" the Chief Minister in the state in excerpts of a Clubhouse chat posted on Twitter by the BJP's Amit Malviya this morning. The bombshell audio clips dropped as Bengal voted in the fourth round of polls and triggered a wave of triumphant posts from BJP leaders who crowed "Game Over, Trinamool".
