From the piece:

"That would violate Mr. Romney’s vow that neither current beneficiaries nor Americans within 10 years of eligibility would be affected by his proposal to shift Medicare to a voucherlike system in which recipients are given a lump sum to buy coverage from competing insurers."

The voucher system doesn't violate Romney's pledge to not change benefits for current beneficiaries.

Romney's pledge to repeal the ACA and it's cost saving benefits for current Medicare beneficiaries is the pledge that is in direct conflict with Romney's pledge to preserve current benefits.

Ryan Medicare savings

The analysis attached to the graphic says "Mr. Ryan’s plan includes the $716 billion saved by cost-cutting under the president’s plan. “Our budget keeps that money for Medicare to extend its solvency,” he said in June. He has also said the money would help reduce the deficit.

It seems that any "deficit reduction" implicitly assumes that the money is needed to pay benefits. But experience has shown that extra payments to insurers were subsidies they needed because of their inefficiency compared to regular Medicare. And the reduction in payments to providers were negotiated with the providers in exchange for a massive infusion of new customers via the ACA.

The headline: Patients Would Pay More if Romney Restores Medicare Savings, Analysts Say

Someone who didn't read beyond the headline would come away with a confused impression that Romney is "restoring" savings with the result that somehow beneficiaries would pay more. But he's promising to repeal the savings, not restore them.

There's also a pretty good Reuters piece here:

the position held by these characters is ridiculious. as baker has pointed out the congressional budget office estimates that vouchers cost $34 trillion more than the current system over a 75 year period. the bottom line on romney is, he wants to drop any benefits to the poor or middle class, so the wealthy will have even more. his greed knows no bounds. he is almost surely the most dangerous candidate every to run for the presidency by a major party. i believe he will probably start ww3.
