Nitish Kumar's victory in Bihar

Nitish Kumar is on top now a days, every person is praising him for getting record mendate in Bihar, but people are just overlooking the fact that total no. of votes in favour of ruling combine is less that total no. of votes opposition parties together got!! Its true that Nitish's development centred governance tilted general public favour in his side but its foolishness to think that Bihar has overcome caste politics, which has been main cause of its backwardness and explotation over so many years. Yes, there is change in wind and may be number of voters must came out of mindset of caste politics and voted for development only but its more an exception rahter than general trend. Otherwise why RJD, LJP and Congress and others got 61% votes compare to JDU+BJP's 39%?? Its clearly a victory of united NDA ( JDU+BJP) over divided opposition.
Other factor being ignored, while praising all over to Nitish, is Sushil Kumar Modi. As leader of opposition and state BJP chief he had built party at grassroot level over many years of Lalu Raj, he was all these years building the party while remaining in Bihar whereas Nitish was there in centre. As deputy chief minister of state for past 5 years, he was also equally contributing in governance. BJP's preference is more impressive in this election than JDU, they got 92% of seats where they contested. Unfortunately nobody giving even 10% credit to Bihar's Modi of BJP for this landslide win.
So Nitish Kumar should perform more on development front if he wants to rule Bihar for longer and he has to keep his ally BJP alongwith. People who are suggesting him to go alone by dumping BJP actually prompting him to do harakiri. Its unity of BJP and JDU got them this victory in Bihar.
