With his ailing father Lalu Prasad Yadav restricting his movements under medical advice, Rashtriya Janata Dal leader Tejashwi Yadav has been suffering from low back pain for the last ten days and both the sisters, Misa Bharti and Rohini Acharya are busy campaigning in their constituencies Patliputra and Saran respectively, and the regional party is now facing an acute shortage of star campaigners. In the BJP camp, Prime Minister Narendra Modi, along with his other star campaigners, has launched a no-holds-barred campaign against RJD in Bihar. On Monday, Modi flew from Patna to address rallies in Saran, Muzaffarpur and Hajipur and landed in Varanasi late in the evening to take out a huge road show.Â
