I think you have to squint pretty hard to see the debt deal as a masterful triumph for Biden over those wicked Republican snollygosters. He had to move from a refusal to negotiate to major spending concessions. He had to give up all the unspent Covid money and back off on tax hikes. They even cut back on the money for new tax collectors.
Bipartisanship was more of a last resort than a goal he achieved.
