With his father’s party of marginalized voters, Tejaswi Yadav, 29, is taking on the BJP. As the helicopter hovers, the crowd, having waited two hours in the sweltering heat, scrambles for a glimpse. Amid the pandemonium, men raise slogans praising Tejaswi Yadav, the 29-year-old with facial hair stubble and an intense look who descends from the chopper and makes his way to the stage. To witness the shoving and jousting, this could be a rock concert. But Tejaswi — as he is widely known — is no rock star. He’s a political neophyte who’s battling to keep alive a storied Indian political legacy. He’s also the face of the opposition challenge to Prime Minister Narendra Modi in Bihar, the country’s most densely populated state of 104 million people. |
