There are only two options left for Nitish Kumar. First, he should show the political wisdom of 1995 if he wants to cling to power and reconcile himself with a scenario wherein Narendra Modi will be the PM candidate of NDA.
Second, he should be upfront on not compromising with his stated position on Narendra Modi even if it costs him politically the way it has happened in Maharajganj. May be that will help him in galvanizing anti-Modi forces under his own umbrella and he would be in a position to offer an alternative to the people of Bihar in upcoming Lok Sabha elections.
Unfortunately, Nitish Kumar is left with no third viable alternative. Any tie-up with Congress will not bear desired fruits under present circumstances as has been proved in Maharajganj by-polls where the Congress candidate has performed poorly and has been relegated to fourth position.
For the time being, Nitish Kumar has fallen in his own trap and it's time for a deep introspection for him.
