I am very happy for Arvind. He could have been a millionaire while doing his IRS job. He left all that for his principles.
He was maligned and constantly criticized. Still his party overcame all the hurdles. His rivals could afford funds(guess where they came from?) which are in orders of magnitude larger than his party's tiny 20 crores(less than budget of a Hindi movie).
I wish nothing but best to him and hope he brings the change that India desperately needs.
