The GOP House passed a bill to raise the debt ceiling, but conditioned upon dramatic budget cuts (i.e. hostage taking).
That led the adult (President Biden) to engage McCarthy, and reach a deal with meaningless budget cuts so that McCarthy can save face. The GOP crazies (hostage shooters) will vote against the revised legislation.
The revised bill will very likely pass, only because more adults (House and Senate Democrats) will vote for the revised legislation in order to ensure that we do not default.
Try to keep up, child.
