I am not really informed on the most current state of Indian politics but my own gut feeling is that this is very unlikely to work. The BJP has entrenched itself pretty firmly from what i have seen so far. This would be like trying to oust Erdogan in Turkey. Despite some significant discontent they both unfortunately still have a very solid base of support, their opposition is weak and the electoral system in many places is heavily rigged in the ruling party’s favor. The advantage in India is that due to its being a federal state there are regions where the BJP just can’t and won’t make any inroads as the local governments there tend to also be very strong, and some of them are quite far left such as Kerala in southern India.
