Nitish Kumar needs Congress

Why does Nitish Kumar need Congress more than RJD?

Given that Rahul Gandhi is still reluctant to take over as the Congress president with the organisational elections in the grand old party fast approaching, it is unlikely that he would like to be projected as the opposition's prime ministerial pick. He would rather happily leave it for Kumar provided the JD(U) leader sticks to the present arrangement till 2024.
