As someone with deep ties and frequent visits to Delhi city, I can categorically state that he is enjoying fruits of work by the central govt, rather than his own government’s contribution. In spite of being in the opposition, the “dictator” is delivering more for dilli than dilli’s own CM.
One bad summer and the city will not just parch, it will scorch - inspite of Powergrid lending all it can to improve cities’ power supply and how badly monsoon has been hitting the city is no secret even to his die hard supporters. Nothing blocks Kejriwal’s powers in water/sanitation, power supply, healthcare, etc. But he has little to show for work, despite claiming that the city has a surplus budget.
Though, how far Delhi’s CM has gone to block funds to MCD, DMRC, NCRTC, etc is matter of public knowledge, well documented even by friendly media - where his govt spends hundreds of crores to advertise.
Do yourself a favour. Just look at data of how many new employees has Kejriwal govt recruited in delhi’s power sector or delhi water services or teachers in delhi schools in its 10 years… or new doctors? For context, Delhi’s unemployment rate is higher than the national average (twice, as per some yardsticks).
TL;DR : Kejriwal is a populist, with little to show on ground as work.
