I think left should stop barking against 123 just to show that they are different from congress. However they will support congress with a fear of BJP comming back which will be their argument in near future. They are nothing but chamcha of congress with another offshoot & different name. One lecture of Sonia will cool all of them. After all they enjoy being sided by congress than BJP. They will back congress 200% at the end of day and take credit to maintain the stability of Govt.
