If they want to get serious about healthcare here are some considerations. Healthcare is available to everyone, right now. That's right. You get hurt, you need to be treated, the ER must see you and treat you, period. You want healthcare made available to everyone, it is, right now. So two of their major talking points are non-starters. Everyone gets seen, and everyone can get healthcare if they want it.
So what is the problem? Cost. For some people healthcare is simply out of reach. Some choose to prioritize it lower than other things. But the main factor is cost. How can we not only control the ballooning costs, but reduce them. The answer to that, I believe lies outside the medical field - in law. Tort reform would go a long way to towards reducing healthcare costs. Not just through reduced malpractice suits, although that would certainly help. But also through reduced tests and procedures. Chances are, if you go into a medical facility for something even as relatively cut and dried as a broken bone you will be subject to a battery of tests. At least an X-Ray, maybe an MRI, probably a blood test, etc. etc. Why? Because medical personnel, their hospitals/clinics, an their insurers fear lawsuits. Better to blow a few hundred bucks on un-needed tests just to CYA. That way if for some rare reason something else happens or goes wrong, you won't be seeing that person in court. Well, you probably will. But at least the Dr. and facility can make the argument they did everything in their power to diagnose and treat you.
Reduce the threat of frivolous lawsuits and you'll see not only malpractice insurance costs directly reduced, but also many of the secondary tests/costs Dr.s and facilities mandate.
