MIM is a regional party, its only recently they started to expand and field candidates with some success in maharastra. they will face stiff competition from other muslim parties like muslim league in kerala. There is no way they can penetrate kashmir for example, the local parties are just too strong.
the places where riot happens, if muslims are minority, they do tactical voting(voting as a block to defeat bjp, that candidate could be congress, sp or bsp depending on area)
