First Obamacare so far works better than any alternative including the current Republican Single Payer Bill. Go to an insurance calculator site and see what you would pay without Obamacare and without coverage you now get at work and compare it with what you pay for the Republican alternatives. No one wants to repeal without a replacement— not even the Republicans because it woud cause chaos and hardship for millions who would lose coverage with nothing to replace it. That is what is so bad with this bill— it is a Single Payer plan because it defunds Obamacare and Medicaid but pays out the money to the states to hand out and figure out how to do that— it is Federal Single Payer giving to the states to distribute a lot like medicare, but without the structure of Medicare. On top of that it retains the Obamacare special taxes which are used to fund the handouts to the states, so no savings to the national debt happens.
