I think Tettar is going to lose MLA elections because so far he hasnt proved himself to be a very bright politician. He is head of the village because before him his ancestors had been ruling this place. Technically, democracy began here only after people voted Nimki to power. Prior to that they didn't know they have any other choice.
This point is also proved by the fact that Tettr has appointed an amateur Rituraj as his political advisor. For a five term veteran politician a newbie/ inexperienced lawyer should be the last person as a political advisor. Its okay of he is handling Tettar's legal matters and being his spokesperson but Tettar being dependent on his damad for political advices shows how immature he is as a politician.
Lastly, I would say his whole clan has ho idea how SM plays a big role in elections these days. Nimki used SM to her favour but Tettar and his ilk is still dependent on bhopus and cycle rickshws for prachar. SM also is very powerful in making ot breaking his image. Today every incident is recorded and shared in media. So, this type of kands that Babboo and his mother do publicly wont be whitewashed with a Holi celebration. Also, castr politics is very powerful in India and particularly in Bihar. Unfortunately he has done very little in this regard.
