Why did Narendra Modi chose hatred politics for Bihar ?

I was watching Narendra Modi Gaya’s speech on 8^th Aug 2015 and certainly a thought came in my mind why did Narendra modi chosen hate politics for Bihar election whereas he has taste big loss in Delhi election of doing negative politics.

I could figure out some of the key issues which could have agenda in Bihar assembly election 2015 which are list below. I have also tried to analyse why Narendra Modi didn’t pick up these agendas for this elections.  

• Development in past one year of Modi’s regime Vs Nitish Kumar

Now the key problem was the theory which articulated before Indian voters during 2014 general election. Narendra Modi has hardly be able materialize on ground level whereas Nitish Kumar could materialized successfully some of his Development theory. Which lead Narendra modi to attack on Nitish Kumar’s political DNA.

• Corruption free Govt to Bihar

Narendra modi could have come up with agenda of corruption free Govt the state but the his own party men are involved in series of charges could have bounced back hence, he chosen  Jungle Raaj vs BJP Raaj. 

•  Communal harmony and  equality to society

Narendra Modi had an option to opt communal harmony is state to consolidate 16% Muslim voters but   BJP can’t beat the Nitish Kumar’s secular image. Specially when in last one year country has witnessed number Pro-Hindutava movement.

• Creation of New Jobs

Modi govt has been failed to create Jobs in past  one and half years and it could have difficult to convince the Bihari Voters. 

So, Narendra Modi jee selected a hatred politics for Bihar election but he and his alliance need to understand advert of hatred politics are listed below. 

1.       if Bihari Community will conceive Nitish Kumar’s DNA as insult of Bihari community then this election will take an edge Bihari Vs BJP. There is also possibilities that Bihari community may gate pro Nitish Kumar being they has witnessed insult of Biharies at many occasion in states like Maharastra , Gujrat , Punjab etc.
2.       If insult of Lalu Yadav will perceive of Yadav community as insult of Yadavs then then Mahagathbandhan will be able to consolidate 14% Yadav vote banks
3.       Since in Mahagathbandhan  RJD, JDU and Congress all three got  maximum share of  Muslim Votes because of their pro-secular image it  seems they will be able to bank 80-90% Muslim vote in favour of alliance.
