On Thursday, House Republicans released their “Pledge to America,” supposedly outlining their policy agenda. In essence, what they say is, “Deficits are a terrible thing. Let’s make them much bigger.” The document repeatedly condemns federal debt — 16 times, by my count. But the main substantive policy proposal is to make the Bush tax cuts permanent, which independent estimates say would add about $3.7 trillion to the debt over the next decade — about $700 billion more than the Obama administration’s tax proposals.

True, the document talks about the need to cut spending. But as far as I can see, there’s only one specific cut proposed — canceling the rest of the Troubled Asset Relief Program, which Republicans claim (implausibly) would save $16 billion. That’s less than half of 1 percent of the budget cost of those tax cuts. As for the rest, everything must be cut, in ways not specified — “except for common-sense exceptions for seniors, veterans, and our troops.” In other words, Social Security, Medicare and the defense budget are off-limits…

So the clear and present danger isn’t that the G.O.P. will be able to achieve its long-run goals. It is, rather, that Republicans will gain just enough power to make the country ungovernable, unable to address its fiscal problems or anything else in a serious way. As I said, banana republic, here we come.
