What’s new: Kejriwal is a risk-taker, a gambler. This is why he took on Sheila Dikshit in December 2013, and Narendra Modi in Varanasi. He has also attacked big business by naming Ambani and Adani repeatedly. His attack on Robert Vadra brought genuine scrutiny of his alleged misdeeds. And so did his attack on Nitin Gadkari. Irreverent bravery of this kind appeals to the underclass and the underprivileged. What Arnab Goswami is to TV Kejriwal is to Delhi’s politics. Also, his attacks empower the media to do its job better, and not bury issues in a conspiracy of silence.

What’s not new: Intemperate attacks are not new in Indian politics. There is almost no party which has not attacked rival politicians or targeted businessmen in some way or the other. The late YS Rajasekhara Reddy targeted media that was close to Chandrababu Naidu, and also businessmen connected to those media. J Jayalalithaa targeted the Sun TV group, and the Marans’ businesses. The danger in this kind of targeting and mud-slinging is that it can permanently alienate business in general, making the prospect of genuine entrepreneurship without cronyism difficult. Kejriwal’s attacks will force businessmen to think they need political protection, not the other way round.

What’s new: Kejriwal has redefined street politics with doses of smart tactics and strategy. He has tried to use street power to attack the system. In his 49 days as CM, he exhorted ordinary people to do stings to check the corrupt, and, in one memorable midnight caper, his law minister tried to get the police to check alleged prostitution involving African women. That raid ended in ignominy, but the fact remains that Somnath Bharati tried to get the police to respond to the concerns of the community they were meant to be responsive to.

What’s not new: There is no Indian party that does not practice street politics. All real political issues are often settled on the street, and finally find expression through the ballot box. Mamata Banerjee did so over the land acquisition issue and tossed the Left out of power. The Shiv Sena routinely takes to the streets on Marathi manoos issues, and the BJP on real and imagined slights to Hindus. The “secular” parties regularly encourage the minorities to protest on the streets to seal this vote bank. The problem for Kejriwal is that street politics ultimately leads to kangaroo courts and vigilantism – as Somnath Bharti found out to his cost. It is easy to agitate mobs, tough to rein them in.

What’s new: Kejriwal has by and large brought forth real issues, and largely eschewed sectarian politics. This is one reason why Muslims are looking at AAP as a potential alternative to failed “secular” parties.

What’s not new: In the last election Kejriwal did dabble with minority politics by schmoozing with dubious clerics, but he did not carry it too far. But AAP is untested beyond Delhi, which is largely urbanised and hence less vulnerable to excessive sectarian appeal. Moreover, sectarian issues of caste and religion will not go away when his party tries to expand. One cannot be sure that Kejriwal will completely break away from the old politics of division practiced by all parties.

What’s new: Kejriwal has galvanised the middle classes, something that most political parties (barring the BJP) have ignored in the past. Through his 49 days in power, he has probably split the middle class by retaining the lower end of this class and losing the upper end by focusing on protests instead of governance.

What’s not new: Like every other party, Kejriwal has indeed accepted the need for divide and rule. This has been done by dividing his support base on the basis of class. He has also tried to split business by appearing to be on the side of small business, and being avowedly anti-crony business. But even in big business, he has targeted some and spared the rest. This has to be deliberate, for the truth is few Indian businesses have clean hands. He must have thought that taking on everybody would leave him without resources and friends.

Here’s the bottomline: Like May 2014, which was about Modi, February 2015 is about Kejriwal. Whoever wins, this is the real issue that will be tested.
