Forgive me; I say this for descriptive value, not to be pejorative: gman is playing a mug’s game, and you’re falling into the role of the mug.
The game goes like this:
I point to the plain language of the law. Instead of concurring, gman claims that the plain language isn’t the meaning at all, and that there’s no way to settle our disagreement.
I point to a ruling by the FEC - the statutory authority under the law, not a prosecutor - which upholds my meaning. Instead of granting the meaning, gman says the FEC is also wrong and that no judge would uphold their ruling.
If I were to point to a case where a Federal judge upholds the ruling, gman will still not grant my meaning; instead, he will say that the judge is wrong, and that he would surely be overturned on appeal.
If I were to point to an Appeals Court ruling which confirms my understanding of the laws, he would simply laugh, declare the ruling wrong, and opine that SCOTUS would surely overrule.
If I were to point to to a SCOTUS ruling confirming my understanding, he would simply say that it was wrongly decided by a prior liberal Court, and that the current Court would take a different view.
If SCOTUS were to uphold my understanding tomorrow, he would laugh, and say ‘oh, but that case was about a list of conservative activists, and we’re talking about oppo research, a completely different thing, and obviously that ruling doesn’t apply here.’
The point here is nothing is ever finally decided, because there is always the remote possibility that a future Court will go the other way. This does not mean there is no law. The statue means what the FEC says it means, unless and until a court says it doesn’t. The FEC’s ruling has the force of law, or nothing at all has the force of law.
