BJP is making a big push again for the concept of "One nation, one election" or holding simultaneous elections for LS and state assembly election by keeping the length of the LS and state assembly fixed and synchronized.

The BJP have been push things for at least 20 years. The theoretical reason is that it would save on resources. But I think the real reason are the following: The BJP noticed that since the early 1990s the BJP vote share drop-off in assembly elections relative the the most recent LS election on the whole is worse than INC or other regional rivals. So the BJP want to nationalize the assembly elections at a time that the BJP clearly have an edge at the national level.
In terms of execution this would require a constitutional change and I doubt it will be easy to do and most likely will not take place.
This is the first formal step towards dictatorship. And as usual the opposition doesn't/can't care.
To demonstrate the gravity of the situation that everyone seems to be ignoring: This is akin to if the Republicans were to eliminate midterms and off-year elections altogether.
