Democrats are troubled by the inconsistency of Republican lawmakers who approved a major Medicare expansion six years ago that has added tens of billions of dollars to federal deficits, but oppose current health overhaul plans.
All current GOP senators, including the 24 who voted for the 2003 Medicare expansion, oppose the health care bill that's backed by President Barack Obama and most congressional Democrats.
The Democrats claim that their plan moving through Congress now will pay for itself with higher taxes and spending cuts and they cite the nonpartisan Congressional Budget Office for support.
By contrast, when Republicans controlled the House, Senate and White House in 2003, they overcame Democratic opposition to add a deficit-financed prescription drug benefit to Medicare. The program will cost a half-trillion dollars over 10 years, or more by some estimates.
With no new taxes or spending offsets accompanying the Medicare drug program, the cost has been added to the federal debt.
Some Republicans say they don't believe the CBO's projections that the health care overhaul will pay for itself. As for their newfound worries about big government health expansions, they essentially say: That was then, this is now.
