Robert Greenstein graphs it:
House Budget Committee Chairman Paul Ryan’s budget plan would get about two-thirds of its more than $4 trillion in budget cuts over 10 years from programs that serve people of limited means, which violates basic principles of fairness and stands a core principle of President Obama’s fiscal commission on its head.
Agreed. Which is why the Democrats now need to provide a way to get equivalent savings by fairer means. If they could stop politicking and demagoguing, this is a major opportunity to contrast their vision of shared sacrifice with the GOP's. My support for the Ryan plan is highly qualified but still there because he has indeed put a great deal on the table and stood behind it. It would a terrible shame if the Dems didn't match him dollar for dollar with different priorities, rather than sit back and merely throw brickbats at the evil GOP.
