Ok lets talk about specific mismanagement....
1- Brought down power bill so drastically and with so much adhocism that now the power bill is set to double this summer.
2-Offered 700L free water initially and suddenly put in weird conditions before people coudl realize. Many Delhiites are till date fighting the case of ballooned water bills.
3- Crime rate against women trebled during his tenure in which he could do nothing (because of Delhi's governance structure, but then why did he promise what he cannot commit).
4- Said that in 15 days, will bring Jan Lokpal independently as soon as coming to power but instead, took support of the very party that Delhiites wanted to punish, thereby cheating their trust.
5- Hooliganism among AAP ministers was the highest including the worst ever case of sexually harrassing of foreign women by a state law minister.
6- Spent all his time doing Dharnas and movements around the state despite being the CM. Cost Delhi government more than what usually it costs giving CMs security.
7- These movements cost endless delays, traffic jams and de-tours, harassing and troubling daily commuters.
When coming to power and wanting to bring change, it must be swift but systematic. We are talking about multiple sections of the society to be changed which has to have a planned, calculated strategy with a team that is willing to handle.
The very moment Kejriwal took Congress support and answered media that Lokpal is the solution for every damn problem, people began to open their eyes.
Oh and before you jump to criticize anyone, AAP has seen more internal disillusionment than any other group.
Because those who joined AAP as volunteers and workers were honest young people of the city wanting to really bring a change.
Till now whatever physical attacks or insults AK has got, are all from their AAP volunteering or contributing groups who have been cheated with his lies.
