The vast majority of critics of the bill have not read it. They depend on analysis from selected pundits and so-called authorities. The bottom line is that the GOP had better come together and develop a consensus on a plan or they will face carnage in 2018. The perfect is the enemy of the good. Compromise must be found or the GOP can commit political suicide.
The Dems never has this problem. They know how to govern even if they are in the minority.
