BJP lost the election in Bengal and Mamata Banerjee party TMC won the election but Mamata Banerjee lost his own seat, Suvendu Adhikari won the election from the Nandigram. BJP was sure before the result and his leaders also said we will form a government with a good number of margin. But the things happened in opposite ways  BJP lost the election. BJP lost their election because of many factors like BJP's direct attack on Mamata Banerjee's profile. BJP was unsuccessful to crack the vote bank of Mamata Banerjee, BJP did not repeat the performance like the 2019 Lok Sabha election at that time Bjp gain a lot of votes and seats. The BJP had bound its hope on the polarization of Hindu votes and the consolidation of the SC voters. It continues to see whether Muslims would pull it off for the TMC or SC for the BJP. Finally, it seems that while the Muslims set their weight behind Mamta, the SC voters did not connect in the favor of BJP. 

This is the biggest setback for the BJP because fully focus on that election and BJP did aggrieves campaign against the TMC and Mamata Banerjee. The BJP was only focusing on the Hindu vote bank and said that Mamata is a pro-Muslims she did not focus on the development. The vote of the left parties was shifted towards BJP in the Lok Sabha election but these not happened in the assembly election. PM Modi did a lot of rallies in Bengal during the COVID time and people take it in a negative way because in the other part of the country are suffering through COVID-19 and voters understand this thing. 

And Violence is part of Bengal politics because without violence the election did not complete according to history. The many TMC leaders join the BJP before the election, this strategy was also failed but increase vote percentage as compared to the previous election. The TMC strategy Prashant Kishor knows the working style of BJP, and his strategy played an important role in this election. Many senior leaders, central ministers, and chief ministers of other states did campaign in this election but on the other only one lady “ Mamata Banerjee ”. BJP fight this election full of potential and used all its power but in the end, BJP lost the election. One other Mamata Banerjee played emotional cards, she did the whole campaign in a wheelchair.
