- The US parties almost entirely ideologically swapped sometime in the 19th century. Some claim it happened with FDR in the 30s, others claim it didn't "really" happen until LBJ in the 60s. Everybody acknowledges it happened. What a "Democrat" did in 1913 is irrelevant.
- Congress dictates budgets, not the President. The President has veto power (which can be overruled by Congress), but nothing more.
- The modern US economic system enabling us to go arbitrarily far into debt only began in 1971, when we defaulted on our obligations under Bretton Woods.
- The total deficit under Trump was $5.6 trillion, under Biden it was ~7.6 trillion [1]. I assume the author was looking at delta debt and then 'inflation adjusting' it... ugh.

That's just the basic historic/factual backing. The "stats" are even worse, but enough is enough. In any case, the issue is not what happened in 1913 or even Trump's first term, but what is happening now. Trump's first term he promised to do what he's doing now but instead just mostly carried on the military machine (at least without starting any news wars, which was nice - though he was trying his hardest with Iran) and filled his entire cabinet with political establishment types who did their thing.
Trump 2.0 seems to have genuinely gained some sort of messianic delusions, probably from the attempted assassinations, and is actually doing what he said he would do before. And those current actions are what is really changing the game like nothing that's happened in decades.
