There’s nothing in these Democratic objections, however, that couldn’t be creatively finessed. You can claim you haven’t actually “cut” a benefit, for example, if what you’ve done is restrained the rate at which its cost will grow. You can offset spending with new revenue, and you can do so in a way that gives low-income taxpayers a break. Democrats left the door open and these options could have been explored.

The story on the Republican side is entirely different. There are ways to finesse a “no new taxes” pledge, too. Instead of raising tax rates, you close loopholes in the name of reform; you add an enhancement here, a “user fee” there, and you can manage to get the revenue you need and still claim you haven’t voted to raise taxes.

But Republicans are taking the position that not a cent of new revenue can be raised, no matter the euphemism. Some Democrats, yes, are being scratchy and cantankerous. But Republicans are refusing to negotiate at all. That’s not the same thing.
