You are correct in that Democrats are always in lockstep and that Republicans disagree with each other on all kinds of issues. Remember there was no debate of issues in the passing of ACA, Democrats passed an unread law on the orders of their leaders. The government of all Progressive paradises are also in lockstep with each other. It is called totalitarianism. Obamadontcare was the finely crafted plan of those who wish to enslave. Progressives have murdered millions of their countrymen throughout history. It is inevitable, when government is the most important thing, what value do people have? The progressive growth of government is the goal of Progressive government. When Progressives run out of other people's money, mass murder and mass starvation occur. It is a correction for Progressive government since they remains in  power, only the people suffer. (USSR, Nazi Germany, Maoist China, North Korea, Cambodia, Cuba, and Venezuela are just a few examples of Progressive governments).
