While the Constitution doesn't explicitly say that the Executive has immunity from prosecution, it never fucking needed to, because in 200+ years no executive has ever weaponized the Judicial Branch against political opponents and policies they don't like. Even as Potato opened our borders and refuses to follow the law no one is trying to use the Judicial to attack him.
Honestly, I was not sure how this bout with communist lawfare would play out. I figured it would be a tit for tat tell we devolved into violence and commenced to killing each other. A strong and decisive ruling like this may very well end it, but I did not think the SCOTUS, being as already politicized with three partisan hacks on it would rule reasonably and follow the intent of The Constitution. No surprise that the three brain dead women have zero legal arguements and make brazen political statements in the desent.
They may have actually saved us from further becoming a banana republic this whole thing ending in civil war.
