They only appear to want it dead. Do they have other policy ideas? Serious question.

The ones I'm aware of are a suite of market-based ideas that they believe will lower the cost of healthcare generally, and eliminate inefficiencies in the market. Things like medical malpractice reform, increased price transparency, greater portability/control for individuals to manage their own healthcare dollars (like healthcare accounts), states offering insurance policies across state lines, and the like. The idea being that high medical costs are the result of friction in the marketplace and/or the cost of defensive medicine/recordkeeping, so that measures that grease the wheels will lower costs.

Like I said, none of those things are really workable. Some are politically unpopular; others are just not likely to do very much.
