Republican attacks on President Obama’s plans for Medicare are growing more heated and inaccurate by the day. Both Mitt Romney and Paul Ryan made statements last week implying that the Affordable Care Act would eviscerate Medicare when in fact the law should shore up the program’s finances.

Both men have also twisted themselves into knots to distance themselves from previous positions, so that voters can no longer believe anything they say. Last week, both insisted that they would save Medicare by pumping a huge amount of money into the program, a bizarre turnaround for supposed fiscal conservatives out to rein in federal spending.

The likelihood that they would stand by that irresponsible pledge after the election is close to zero. And the likelihood that they would be better able than Democrats to preserve Medicare for the future (through a risky voucher system that may not work well for many beneficiaries) is not much better.

THE ALLEGED “RAID ON MEDICARE” A Republican attack ad says that the reform law has “cut” $716 billion from Medicare, with the money used to expand coverage to low-

income people who are currently uninsured. “So now the money you paid for your guaranteed health care is going to a massive new government program that’s not for you,” the ad warns.
