Cracks are not in UPA but in their mindset. Is CPM trying to scare Congress with its intention of aligning with regional parties and forming a third front. Prime minister will be "humble & sleeping H Devegowda" and agenda will be to drive India again in to stone age.
If such third front rises from ashes of UPA, it would be saddest day because they would UNDO all the good work done by NDA & UPA in last few years.
God save us from catastrophic third front. Let this government continue, at least it is not as bad as third front would be.
