I've actually been trying to follow this case. Charge stacking which I am discussing is a thing. It's not something I cooked up. Countless law journals including the Harvard Law Review discuss the issue in a negative light.
The 37 counts has 31 counts of willful retention of national defense information. Thirty-one counts don't add a whole lot beyond the first count and it is just noise in the overall case against Trump. Per the Harvard Law Review: "Charge stacking is not new, and it can happen to anyone — no one is safe from the risk that government can “divide crime and multiply punishment.” Further from the HLR: "It can happen to any defendant, regardless of social class or era...........In the modern era, celebrity chef and businesswoman Martha Stewart’s five-count indictment for a “tenuous” case of lying about insider trading has led some academics to call for a limiting “law of counts” more broadly."
Perhaps you are arguing this from a different angle. I have no problem with all the charges in themselves. I find the six other charges more compelling than 31 counts of willful retention of national defense information.
Americans can hold two opposing thoughts that what Trump did was a crime under the law and the DOJ/Special Counsel might not be making unbiased decisions in this case. The prosecutors don't have to be politically biased. They can simply be pissed off at Trump's defiance and his antics.
