BJP had no Option but to break Shiv Sena Alliance

The elections to Haryana and Maharashtra are on October 15, 2014. The most un-expected things have happened. In Maharashtra, the 25 year old iron alliance with the Shiv Sena was broken.  This sudden situation has surprised everyone.  You see, the BJP did not act   as it was expected. The BJP refused to be insulted and refused to succumb to threats. The problem with threats is sometimes threats do not work.  

Ideally, BJP which is in power in Delhi needed to have Shiv Sena in Maharashtra to win state elections.  If the Congress party forms a government in these two states, it will be a major setback to BJP.
