Do you have any proof to the contrary or just more spit and froth and anger?
Why can’t you prove it untrue if it’s so obvious?
Well, that's not how "proof" works. One does not prove something untrue. One proves that A causes B. Simply because it is true that B often follows A, that does not mean that A causes B.
For example, all serial killers in the last 300 years have eaten bread, therefore bread causes some people to become serial killers. Those two things correlate at virtually 100%, so serial killers MUST be caused by eating bread.
Of course, that is untrue. But, it is not meant to be true, it is meant to show you the difference between correlation and causation.
You can show that sometimes there are Democrat presidents when deficits fall, and sometimes Republican presidents when deficits rise. Those are correlations. However, that those two things happen in some kind of correlation does not prove a darned thing about the cause of the deficits' trajectories.
To make your point valid, you have to show what specific policies each of those presidents had that had the definitive impact, barring all others, on deficits. For example, every Congressperson must be the same, with the same attitudes and voting histories and influences on other Congress people. The state of the economy which is NOT under presidential control (i.e., all of it) must remain constant. Roughly 1,000,000,000,000 other factors must all remain constant.
What you have is a single piece of information that shows......nothing. Unless and until the president is 100% responsible for the economy and writing/passing/enforcing all aspects of taxation and government spending, you have a correlation without causation.
So, I'm not sure what else I can tell you other than all of this obvious information you should have understood since junior high school. If you still don't get how your claim is woefully invalid, I really can't help you any more. I have explained it to you in excruciating detail, you have to meet me half way at least and
think.
BTW, did you look up to see who had control of congress those periods?
