The respected CM has not been able to do much for the city in terms of its needs (read infrastructure). So what else can you expect from him.
25 years from now you can read in history books it was because of the then CM Dharam Singh that Bangalore got such an internatinal status. He did so many things for the city that the Karnataka state could never give him back in kind.
SOS Request:
Kindly don't change the name of the city. Bangalore looks much more cosmopolitan and global than Bengaluru. With the world shrinking by each passing year, I don't see what reasoning can you give to enhance the regionalism.
