Let's not forget that it has historically been the Republicans that have blown up the national debt. As for your anticipated remark about Obama, let's also not forget that he inherited a dumpster fire from W the likes of which have not been seen in our lifetimes.
I will again note your forgiveness for Obama driving up the debt because of an excuse you have determined is acceptable, but COVID is Trump's fault, 9/11 was Bush's fault, and I'm sure if we go back far enough we can find things that are every Republican President's fault while at the same time forgiving Democrats for similar things.
Let alone the fact that spending is actually controlled by Congress, as is the budget and you really need to take a look at what programs increased markedly and why. It wasn't Bush's decision to spend during the all Democrat House, Senate and White House.
Instead, you need to accept that both parties spend like drunken sailors. The only difference between them is that Republicans are supposed to be the part of fiscal conservatism - which makes them worse in this regard because they are full of shit.
