Bihar: Nitish-Lalu's Mahagathbandhan on verge of split?

Mahagathbandhan has been experiencing several ups and downs because of the President Elections 2017. Nitish Kumar is supporting NDA's Presidential candidate Ram Nath Kovind, however Lalu Prasad Yadav is inclined towards UPA's candidate Meira Kumar, which is likely to cause a rift in Nitish-Lalu's Mahagathbandhan.
