I hate to defend Biden, I truly do, but your math is so faulty it can’t be avoided. And I’m not really defending Biden anyway, I’m defending the intergity of the math when it comes to these types of calculations.
Specifically, national debt with regard to a President is not calculated simply by starting the count on the day that person becomes President, and ending on the day the leave office, as you are always clearly attempting to do.
It is instead based on how many obligations that President assumed while President, even if the spending takes place after they leave office. Likewise, any Presidents contribution to the debt isn’t based on obligations made by previous Presidents.
Now typically, obligations are only for one year, and therefore do often align with that President’s term. But not always. For example, the tax cuts that Trump signed into law actually were being paid for in many instances by expected debt after he left office, and are therefore added to his contribution to the debt, verses added to the Presidents that come after him.
It takes studies from offices like he congressional budget office to accurately come up with figures attributed to actions by a President. You calling someone else a liar when you don’t even understand the basics of these calculations is shameful.
I provided links that provide the debts they list year by year, and was used to come up with the 8.4 trillion debt they have attributed as being Donald Trumps addition to the national debt.
You have proven nothing. All you have done is make a statement. So, actually prove your argument.
