Firstly, Left is not a part of UPA. It is supporting UPA externally. Congress has regional support already from NCP, DMK, RJD, various North Eastern parties, besides its own party ruling many states (some with regional allies). With Kerala, Tamil Nadu, entire North East, majority of West Bengal, Maharashtra, J & K, it already has a huge vote bank. Besides rapid industrial development and improvement in living standards in urban areas would definitely please enough the common Indian to relect this government. Debt waiver will certainly cause a major turn around in farmer's opinion of the current government. But all said and done, everything is just analysis. Last time the UPA showed us a miracle, this time we have to wait and watch.
