The real behind-the-scenes debate in DC this month is about, first, the best mechanism to transfer funds (direct subsidies, state subsidies, Federal reinsurance pool for the sickest cases, etc ... each of which create distinct winners and losers whose lobbyists are currently out in force), and second, how much of an annual budget deficit the fiscal-hawk Republicans (now led by Rand Paul) are willing to tolerate.
The longer-term solutions have much more to do with diet, lifestyle management, and other behavioral health issues than with access to providers and drugs (e.g. look up how much of last year's medicaid/medicare budget was spent on type 2 diabetes treatment alone). Unfortunately it doesn't seem like we can tackle these issues at scale until after the current debate on affordable universal access to care is settled.
