Only within the context of perceived possibilities supposedly hemmed in by "beltway realities"

NRO gives Ryan's 2015 budget plan a good review, although the editors do acknowledge its modesty:

The most important of the ideas Ryan has repeatedly proposed and gotten passed in the House is his Medicare reform. The combination of America’s aging population and our broken health-care system will be devastating to our federal budget and the economy unless we do something like what Ryan has proposed. The president has addressed our national health-insurance millstone only in passing, and with his most familiar — and most historically impotent and inefficient — method, command-and-control economics. Ryan’s plan would introduce competition and innovation into Medicare, cutting costs while providing the same benefits. This time he’s tweaked the plan that already got the endorsement of Democratic senator Ron Wyden, to save seniors money while pushing them toward private plans. Medicare is growing so costly so quickly, in fact, that Ryan shouldn’t wait a decade to implement his plan, as his budget again does.

Medicare isn’t our only unsustainable entitlement, and Ryan is less aggressive on the others: Republicans need a plan on Social Security, and he expects unlikely savings from merely block-granting Medicaid to the states.

Which is why Barracuda blasts it as unserious:

"It STILL is not proposing reining in wasteful government overspending TODAY, instead of speculating years out that some future Congress and White House may possibly, hopefully, eh-who-knows, take responsibility for today’s budgetary selfishness and shortsightedness to do so," she continued. "THIS is the definition of insanity. Do we still not understand how dangerous it is to allow government to grow unchecked as we shackle ourselves with massive debt – a good portion of which is held by foreign nations who don’t necessarily like us?"

"If we can’t balance the budget today, what on earth makes us think it will happen at some future date?" she wrote. "The solution is staring us in the face. We need to rein in spending today, and don’t tell me there is nothing to cut when we know every omnibus bill is loaded with pork and kickbacks."

I'm inclined toward the latter view.  The time for tiptoeing around the sensitivities of FHers just because they happen to be colleagues on Capitol Hill - especially when their Senate majority is probably in its death throes - is long over.
