The judge’s ruling really doesn’t mean much. This will go through many layers of appeals, and ultimately will probably be a song for the Supremes.
As I have noted before, the basis for the case is obvious. If the suit is denied, it means that Joe President can accept any level of bribe from a foreign nation as long as he does it though a business. In that case, a President could not accept a billion dollar personal bribe from the country of Musialstan, but he could own an antique store with one item on sale – an old beat-up couch, for example, worth five bucks. As long as he lets his son run the antique store day-to-day, the son can slap a billion dollar price tag on that couch, and sell it to the Musialstanis. That’s exactly the same in intent and effect as the billion dollar direct bribe. It seems to me pretty obvious that we can’t allow our President to be in that position.
That said, it doesn’t matter that the case obviously has merit. What matters is what the courts ultimately rule, and I can’t predict that.
