The big bad event of last week was, of course, the Supreme Court hearing on health reform. In the course of that hearing it became clear that several of the justices, and possibly a majority, are political creatures pure and simple, willing to embrace any argument, no matter how absurd, that serves the interests of Team Republican.

But we should not allow events in the court to completely overshadow another, almost equally disturbing spectacle. For on Thursday Republicans in the House of Representatives passed what was surely the most fraudulent budget in American history.

And when I say fraudulent, I mean just that. The trouble with the budget devised by Paul Ryan, the chairman of the House Budget Committee, isn’t just its almost inconceivably cruel priorities, the way it slashes taxes for corporations and the rich while drastically cutting food and medical aid to the needy. Even aside from all that, the Ryan budget purports to reduce the deficit — but the alleged deficit reduction depends on the completely unsupported assertion that trillions of dollars in revenue can be found by closing tax loopholes.

And we’re talking about a lot of loophole-closing. As Howard Gleckman of the nonpartisan Tax Policy Center points out, to make his numbers work Mr. Ryan would, by 2022, have to close enough loopholes to yield an extra $700 billion in revenue every year. That’s a lot of money, even in an economy as big as ours. So which specific loopholes has Mr. Ryan, who issued a 98-page manifesto on behalf of his budget, said he would close?
