Aam Aadmi Party chief Arvind Kejriwal is set to take oath as the Chief Minister of Delhi on February 16, Sunday. Similar to Delhi elections 2015, Kejriwal will take oth as Delhi Chief Minister at Ramlila Maidan in the national capital. Arvind Kejriwal, engineer, civil servant and Delhi's man with a development agenda, is the David who slayed the mighty Goliath for the second time in five years. The Kejriwal-led Aam Aadmi Party secured 63 of Delhi’s 70 seats, leaving the BJP with seven and decimating the Congress, overcoming the BJP's divisive campaign.

Nine years ago, Kejriwal slipped into the political frame behind Anna Hazare during the Lokpal movement in 2011 before quickly enlarging his canvas, first as a satyagrah activist and then as founder of the cleverly named Aam Aadmi Party that took on the might of the BJP to reclaim Delhi for a third time on Tuesday.

The name of his party as carefully chosen as his public persona perhaps, Delhi’s 51-year-old chief minister is the embodiment of the everyday man but one who has tailored his politics and campaign in keeping with the times.

As he emerged on the victory stage to loud cheers from his AAP supporters and shouted “Bharat Mata ki Jai”, ‘Inquilab Zindabad” and “Vande Mataram” before saying “I love you” to Delhiites, many remembered the earnest activist who went on a hunger strike for a Lokpal bill in 2011.

The year after, in 2012, he started his political party and emerged as a mascot of an alternative brand of politics – and the ‘aam aadmi’ politician with his muffler casually wrapped around his neck, and sometimes his head, oversized shirts and open-toed sandals.

Though his ambitions to make the AAP a national party have not met with much success, the Delhi chief minister's hat is one that will stay -- for the next five years at least.

His effort to be seen as a direct challenger to Narendra Modi came a cropper in 2014 when he contested the Lok Sabha elections from Varanasi. He tried to make an electoral dent in Punjab and Goa in 2017 but that didn't work either. So Delhi it is for the moment.

In 2013, he became chief minister but only for 49 days, images of him sleeping in his utilitarian Wagon R while on ‘dharna’ for a Jan Lokpal (ombudsman) wrapped in a cotton quilt against the cold winter nights making the front pages.

Battling allegations of being autocratic and unyielding in his politics, Kejriwal resigned soon after, only to bide his time till 2015 when he scripted a stunning win to bag 67 of Delhi’s 70 seats.

Earning the moniker ‘mufflerman’ for his fondness for the muffler, Kejriwal runs his party with the proverbial iron fist and has learnt to temper his aggression, say people close to him.

He has mellowed since his days as the rebel leader on a 'dharna', carefully calibrating his political message and refusing to be baited by the BJP which made the anti-CAA protests in 'Shaheen Bagh' its campaign centrepiece.
