Extravagant promises and bluster are the stuff of campaign rhetoric, but the House Republicans’ “Pledge to America” goes far beyond the norm.

Its breathless mimicry of the Declaration of Independence — the “governed do not consent,” it declares, while vowing to rein in “an arrogant and out-of-touch government of self-appointed elites” — would be ludicrous, if these were not destructively polarized times.

While it promises to create jobs, control deficit spending and restore Americans’ trust in government, it is devoid of tough policy choices. This new “governing agenda” does not say how the Republicans would replace revenue that would be lost from permanently extending all of the Bush tax cuts, or how they would manage Medicare and Social Security, or even which discretionary programs would go when they slash $100 billion in spending. Their record at all of these things is dismal...........
