While true, there is another nuance missing here. The deficit was higher in 2020 & 2021 due to the Covid stimulus spending. Looking at 2017-2019 for Trump and 2022-2024 for Biden probably gives a fairer picture of what happened during both presidencies. It's basically been an upward trend since 2015, excluding the Covid outliers.

Yes, that’s why I prefaced my comment with “technically.” To claim Biden grew the deficit, you would have to explain that COVID was some sort of exception and then argue that it still grew in spirit (rather than technically).

Although without COVID Trump was definitely still on track to have significantly raised the deficit since it was falling in most years under Obama compared to 2008/2009 (before COVID he grew the deficit significantly with his first round of tax cuts, just like he just did with the big beautiful bill), and it isn’t clear that Biden would have diverged from Obama without COVID around.
