Paul Krugman, on what I believe is the single most powerful argument for health care reform:

… the proposed health care reform links the expansion of coverage to serious cost-control measures for Medicare. Think of it as a grand bargain: coverage for (almost) everyone, tied to an effort to ensure that health care dollars are well spent.

Are we talking about real savings, or just window dressing? Well, the health care economists I respect are seriously impressed by the cost-control measures in the Senate bill, which include efforts to improve incentives for cost-effective care, the use of medical research to guide doctors toward treatments that actually work, and more. This is “the best effort anyone has made,” says Jonathan Gruber of the Massachusetts Institute of Technology. A letter signed by 23 prominent health care experts — including Mark McClellan, who headed Medicare under the Bush administration — declares that the bill’s cost-control measures “will reduce long-term deficits.”

The fact that we’re seeing the first really serious attempt to control health care costs as part of a bill that tries to cover the uninsured seems to confirm what would-be reformers have been saying for years: The path to cost control runs through universality. We can only tackle out-of-control costs as part of a deal that also provides Americans with the security of guaranteed health care.

And the tactics of those renowned fiscal disciplinarians, the Republican party:

…in the closing rounds of the health care fight, the G.O.P. has focused more and more on an effort to demonize cost-control efforts. The Senate bill would impose “draconian cuts” on Medicare, says Senator John McCain, who proposed much deeper cuts just last year as part of his presidential campaign. “If you’re a senior and you’re on Medicare, you better be afraid of this bill,” says Senator Tom Coburn.

If these tactics work, and health reform fails, think of the message this would convey: It would signal that any effort to deal with the biggest budget problem we face will be successfully played by political opponents as an attack on older Americans. It would be a long time before anyone was willing to take on the challenge again; remember that after the failure of the Clinton effort, it was 16 years before the next try at health reform.

That’s why anyone who is truly concerned about fiscal policy should be anxious to see health reform succeed. If it fails, the demagogues will have won, and we probably won’t deal with our biggest fiscal problem until we’re forced into action by a nasty debt crisis.

This charge is being led by that maverick McCain, who was for Medicare cuts (last year!) before he was against them. So remember guys: the GOP is the party of fiscal discipline…unless a Republican president is office, Medicare spending will win some voters, or scaring old people about cuts to Medicare will derail health care reform.
