This is being done entirely because the Republicans kind of have the house and love being obstructionist. That's the entire reason. If they also had the senate, it would be a trivially passed vote. If they held neither the house or senate, it would be a trivially passed vote.

It has nothing to do with actual concern about our debt, and is entirely about pleasing republican voters who believe that the US congress doing anything is bad, and others who just want to own the libs.

This is basically the only thing that republicans have power over right now in congress, because nobody trusts house Republicans anymore because of just how goddamned crazy some of them are, and how often they go back on their word.
