The core of the problem with the U.S. Healthcare System is that we Americans don't purchase our own Health Care and Coverage, someone else does, and costs are then heavily shifted to those who cannot get someone else to cover them. The U.S. is already subsidizing Healthcare, besides Medicare and Medicaid, there is a huge tax break to affluent and middle class Americans derived from Employer Provided Healthcare. The very structure of this subsidy is sick, the affluent are subsidized while working people who don't have good employers pay through the nose.
I do not believe that either Barrack Obama or John McCain is going to do a good job, other than that the system is so screwed right now (by the Government, not just in its crazy subsidy schemes but by the imposition of the Medicare reimbursement system and the requirement that the lowest rates go to Medicare instead of Payment at Time of Service Customers) that it is nearly impossible to make it worse.
The best choice for fixing Healthcare is Bob Barr. He will push for a return to a real Free Market System which will improve choice and efficiency. The Democratic Congress will insist on a subsidy for the poor. You'll choose your own Health Insurance and your own Providers. If your response is Bob Barr can't win, well neither can John McCain at this point. I've never considered McCain or Obama an option. The Libertarian Party Candidate (Barr) getting %5 of the popular vote is the best option we have.
