Basically Pawar's NCP is trying to reduce the influence of Congress - for example, by not supporting them in last municipal elections. Due to this, ShivSena got the advantage.
As a retaliation, Raj is being used by Congress to gather support from Marathas, to defeat NCP & Shiv Sena in the next elections.
This is clear from the fact that the government refused to arrest him, and the Chief Minister talks in sweet voice about Raj.
ShivSena/BJP have only one chance to win next elections - Bring Narendra Modi for campaigning.
