 What's to stop Biden from ignoring the debt ceiling and continuing to pay America's bills? Nothing. He's constitutionally obligated to do so. And there's at least one precedent for the executive branch doing whatever it takes to avoid default. Guess who said it? During a 1985 budget dispute, Reagan's Treasury Secretary borrowed from the Social Security Trust Fund to keep the nation's bills paid. The U.S. Comptroller General later found this to be illegal but said it was not unreasonable given the circumstances. Will Biden have to resort to such measures? Well, we'll see. The lesson here is there is not a specific date when the Treasury runs dry, just ever more extreme bookkeeping measures to keep paying our bills. If MAGA Republicans don't like this and want to force the U.S. into default, wrecking the economy and putting millions of Americans out of work, let them take Biden to court. Let them demand publicly that he should not honor the full faith and credit of the United States. This is a Republican manufactured crisis. Let them own it.
