Raj are playing marathi cards. he should learn lesson from history. Migrants should not come to Maharashtra/Mumbai if this logic was applied in 500 years before Chhatrapati Shivajis ancestors would have not come to Maharashtra. Shivaji ( a migrant form Rajasthan %u2013 Refer book Shivchhatrapati by Baba Saheb purandare) trained them in warfare and was able to win suntans and mughals. After his death maratha following his war tactics started winning/rulling almost entire India. But they could not make people/warrior of other parts of India( in which Shivaji was master) to be on their side. The effect was seen in Panipat war, in which they could not convince other community to fight form their side.
