Umm, the federal govt already runs a couple of massive health care systems. They don't do what single payer advocates promise, so why do you think that obamacare will?
I think that we should have given obama free reign wrt the healthcare of folks who currently get their healthcare from govt. Yes, military, state, local, and federal employees, Indian Health Service, Medicare, Medicaid, and so on.
We give him 2 years at the current budget then we cut 5% per covered person in the next four years. That's just over 20% which should be trivial given the promises of 30% savings.
If the covered population is better off at the end of that time, we can talk about expanding it.
