Ezra Klein at the WaPo has the definitive statement: Treasury: We won’t mint a platinum coin to sidestep the debt ceiling
And then James Fallows at The Atlantic gives us two sentences:
1) Raising the debt ceiling does not authorize one single penny in additional public spending.
2) For Congress to “decide whether” to raise the debt ceiling, for programs and tax rates it has already voted into law, makes exactly as much sense as it would for a family to “decide whether” to pay a credit-card bill for goods it has already bought.
So, I guess we are back to being held hostage by terrorists/GOP threatening to destroy the world economy unless we all agree to feed granny catfood.
Of course, this is another example of negotiating against yourself before the negotiations begin (having also ruled out the 14th Amendment option), so one can assume that anything that the Administration does end up giving away is something that they wanted to give away.
