Left would have any way walked out under one reason beacuse they need an excuse to fight the Congress in May 2009 . This is what the DMK & PMK did to BJP in 2004 . Walk out win seats & then cling to Power & create Nuisance..
If I were LKA or ABJ I would have voted for the Nuke Deal and Targeted the Congress for the Economic Mess / Inflation etc. Sadwe have politicians & No States men.
