In the USA Today, John C. Goodman writes:

Surprisingly, theres very little difference between the two plans. [Paul Ryan’s & Pres. Obama’s] There is no important difference in Medicare spending — even when the estimates of the presidents budget are made by his own Office of Management and Budget and the costs of the Ryan plan are projected by Ryan himself.Based on what we know, the difference is in how the spending targets are achieved. And even there similarities abound.

Goodman concludes:

The White House and Ryan Medicare budgets don’t differ that much. What does differ is their approach. The president’s approach is inflexible. Ryan’s approach has the advantage of making the cuts less painful by allowing market-based reforms instead of suppressing provider fees.
