Tejashwi Yadav, a first-time legislator in Bihar, proved to be a worthy stand-in for his jailed father Lalu Yadav today as his RJD held onto two seats it had won in alliance with Chief Minister Nitish Kumar the previous time. Nitish Kumar's Janata Dal United last year ditched Lalu Yadav and Congress and reunited with the BJP. The bypolls in the Araria parliamentary seat and the Jehanabad and Bhabua assembly seats were the first since Nitish Kumar swapped partners.
