If its only a voting for deal and left is goverment but against the deal then situation may be different. BJP, shiv sena and SAD are very much happy to support the deal, but if they support the deal then also no benifite goverment will not surviev. And at any cost these partys cannot support Goverment. BJP:- Canot support goverment if they want to support goverment better ask to congress to support from out side and BJP goverment will take deal ahead, any way congress is in trouble and not BJP. Shiv Sena:- Sher jabhi ghas nahi khata, The Balasaheb whole life fight with congress they cannot support congress government at any cost, SAD:- Local politics of PUNJAB and future of SAD didnot permet that,,,,,,, and last option LEFT LEFT :- they cannot support goverment or deal as they are against the INDIA itself and they cannot compromise on there destruction of INDIA policy......
