I don't think any party is blameless in acquiring debt. During the tail end of the last administration there was bipartisan support for extraordinary spending in support of the Covid pandemic, all financed with borrowed money, but in terms of real money, the increase in debt was less than the previous administration.
I think the real question here is just how much additional debt we're willing to accept just as a matter of course. Some seem to think it's no big deal to continue at the the extraordinary rate we're at now, others disagree. Each party uses the possibility of default to both influence total spending and as a political cudgel against their opponents, so there's nothing new there.
But, to go back to your earlier comment, the fact is that Republicans in the House (which is constitutionally responsible for initiating all government spending) have already dealt with the default issue and the Democrats in the Senate and Oval Office are trying to frame it otherwise. Nothing new there either.
